Answer 1

Answer:

Explanation:

The Electronic Configuration of the elements is the arrangement of all electrons of an element in energy levels and sub-levels (orbitals).

There are 7 energy levels, numbered from 1 to 7, and in which electrons are distributed, logically in order according to their energy level. Electrons with less energy will be spinning at level 1. Each level is divided into sub-levels. These sub-levels into which each level is divided can be up to 4. These 4 sub-levels are called: s, p, d, f. In the sub-level s there can only be a maximum of 2 electrons, in p there can be a maximum of 6 electrons, in the sub-level d 10 electrons and finally in the sub-level f there can be a maximum of 14 electrons.

In level 1 there is only one sub-level, which will be the s. In level 2 there are 2 sub-levels, the s and the p. At level 3 there are 3 sub-levels s, p and d. And at level 4 there are 4 sub-levels, the s, the p, the d and the f.

Aufbau's principle is a principle of atomic physics, which explains how electrons are accommodated in their orbits around the nucleus of the atom. This principle states that the filling of these orbitals occurs in increasing order of energy, that is, from the orbitals of lower energy to those of higher energy.

The simplest of the sub-levels is 1s. If you fill the 1s you can start filling the 2s. After the 2s sub-level is satisfied, the 2p can begin to fill and so on. The order is:

In this way, taking into account the atomic number Z of the element (which represents the number of protons of the element, and in a neutral atom it also indicates the number of electrons), the electrons that it has in the orbitals will be placed following the previously established.

For example, for hydrogen, whose atomic number is Z = 1, its electronic configuration would be: 1 s1. Remember that the number 1 that precedes the representative letter of the orbital indicates the level of energy where the electron is located, the letter s indicates the type of orbital where the electron is located, and the exponent 1 indicates the number of electrons that are located in said orbital.

As the Z number of each element increases, the electrons will gradually occupy the orbitals located at the lowest energy levels.

Humans and dogs live together, are they part of the same population? why or why not

Answers

I would think no, because usually when we're dealing with population, we're dealing with one specific species. For example, we don't count the population of all living things in the world. Instead, we divide species up and then determine the population. In this situation, the population of the cats would be 1 and the population of the dogs would be 2. They are not the same species, therefore we cannot determine the population when combining them.

No, humas and dogs are not live together as they belogs from different group of species.

What is population?

Population is the group of species which belongs from the same category and living in a particula area.

Humans and dogs both are living organism but are from the different category of the species. As humans come under the civilized population and dogs come under the animal species. So they are not part of the same population.

No, they are not the part of the same population.

The nuclear mass of 56fe is 55.9207 amu. calculate the binding energy per nucleon for 56fe.

Answers

Fe (iron) has 26 protons,30 neutrons and 26 electrons. In order to calculate the binding energy, first you need to find the total mass of all particles in the nucleus:

26 x mass of proton + 30 x mass of neutron ( all in a.m.u.) = say "m"

Mass defect is m- 55.9207 amu, then convert it into grams and put in equation E = mc2 to get binding energy of Fe.

Divide it by number of nucleons to get binding energy per nucleon.

Answer: The binding energy per nucleon is

Explanation:

Nucleons are defined as the sub-atomic particles which are present in the nucleus of an atom. Nucleons are protons and neutrons.

We are given a nucleus having representation:

Number of protons = 26

Number of neutrons = 56 - 26 = 30

To calculate the mass defect of the nucleus, we use the equation:

where,

= number of protons = 26

= mass of one proton = 1.00728 amu

= number of neutrons = 30

= mass of one neutron = 1.00866 amu

M = nuclear mass = 55.9207 amu

Putting values in above equation, we get:

To calculate the binding energy of the nucleus, we use the equation:

(Conversion factor: )

Number of nucleons in atom = 56

To calculate the binding energy per nucleon, we divide the binding energy by the number of nucleons, we get:

Hence, the binding energy per nucleon is

The nuclear mass of 37cl is 36.9566 amu. calculate the binding energy per nucleon for 37cl.

Answers

The 17 Cl 37 nucleus has 37 nucleons. Thus, making the energy per nucleon is 1.6944 x 10^-19 J/37 nucleons.Energy = 5.09x10^-11 J. So, (5.09x10^-11)/37 nucleons you get a 1.38x10^-12 J/nucleon as an answer.

I hope this helps you with your problem.

Answer: The binding energy per nucleon is

Explanation:

Nucleons are defined as the sub-atomic particles which are present in the nucleus of an atom. Nucleons are protons and neutrons.

We are given a nucleus having representation:

Number of protons = 17

Number of neutrons = 37 - 17 = 20

To calculate the mass defect of the nucleus, we use the equation:

where,

= number of protons = 17

= mass of one proton = 1.00728 amu

= number of neutrons = 20

= mass of one neutron = 1.00866 amu

M = nuclear mass = 36.9566 amu

Putting values in above equation, we get:

To calculate the binding energy of the nucleus, we use the equation:

(Conversion factor: )

Number of nucleons in atom = 37

To calculate the binding energy per nucleon, we divide the binding energy by the number of nucleons, we get:

Hence, the binding energy per nucleon is

The specific heat of zinc is 0.39 j/g*�� c. how much energy needed to change the temperature of 34g of zinc from 22��c to 57��
c. is the energy absorbed or released?

Answers

Answer : The amount of energy needed are, 464.1 J and the value is positive that means the energy is absorbed.

Solution :

Formula used :

where,

Q = energy gained or absorbed= ?

m = mass of zinc = 34 g

c = specific heat of zinc =

= final temperature =

= initial temperature =

Now put all the given values in the above formula, we get the energy gained or absorbed.

Therefore, the amount of energy needed are, 464.1 J and the value is positive that means the energy is absorbed.

I just did this and the correct answer was 464.1 J, absorbed

Compare fission and fusion reactions and explain the difference between their energy input and output.

Answers

Comparing fission and fusion reactions means explaining the terms for better understanding.

Nuclear fission

It is a process in which an unstable nucleus is split into two nuclides and emit/release neutrons. It involves the conversion of a heavier nuclei (unstable nuclei) into two or more small nuclei (stable nuclei) and a large amount of energy is also releases.

Nuclear Fusion

It is a process whereby nuclei joins together into on nucleus. It is a process which involves the conversion of two small nuclei to form a heavy nuclei and some amount of energy is also released.

Now, the difference between the fusion and fission is that:

In Fusion, the energy is given and a small amount of energy is released.

In Fission, the energy is released and a larger amount at that.

A small helium tank measures about two feet high. Yet it can fill over 50 balloons! How can such a small tank contain enough helium to fill so many balloons?

Answers

It will only take a small amount of helium when inflating balloons. For example, an 11" balloon only needs 0.015 m3 of helium. So it make sense, why a two feet helium tank can inflate at about 50 balloons. Also, the size tank (2 ft. high) does not define the capacity of helium it contains.
