Which Statement Describes How An Atom In The Ground State Becomes Excited (2023)

Answer:

The correct option is False

Explanation:

London dispersion forces are a part of Van Der Waal's forces acting between atoms and molecules. They are a temporary attractive force that are formed when two atoms close to each other form a temporary dipole and are hence the weakest intermolecular force of attraction. They are usually the force of attraction found between non-polar molecules.

While a hydrogen bonding a strong intermolecular force (dipole-dipole) of attraction formed as a result of the interaction between an electronegative atom (like oxygen or chlorine) and a hydrogen atom bonded to another electronegative atom (like fluorine). Since, molecules that posses hydrogen bonding have stronger intermolecular forces, they thus possess higher melting point than molecules that possess only London dispersion forces.

The bonding in metals is sometimes decribed as a "Sea of delocalise electrons" this is because the metal atoms are all regularly arranged and are surrounded in free delocalised electrons that can Flow easily between the metal nucli so therefore the answer is the second answer

Hope that helps

According to the electron sea model for metallic bonding, in the sample of metal atom all the atoms contribute their valence electrons which form a delocalized “sea” of electrons. The arrangement of metal ions is in an orderly array with this mobile sea of electrons. The metal is held together due to the attraction between sea of electrons and cations.

Hence, electrons flow easily between metal nuclei is a characteristic of the electron sea model for metallic bonding.

Explanation:

A substance is able to conduct electricity if it has or contains free electrons.

This also means that larger is the atomic radius of a metal lesser will the force of attraction between its nucleus and valence electrons. As a result, it can easily lose its valence electrons.

Therefore, availability of free electrons is easy in that case.

Also, more is the number of valence electrons a metal contains more is the number of electrons participating in conducting electricity.

Thus, we can conclude that a combination of more valence electrons and larger atomic radius factors is most suitable for increasing the electrical conductivity of metals.

Answer: d.) The books have a great deal of inertia and do not move easily

Explanation:

Inertia is the property of a body due to its mass. A heavy object requires more force to be pushed or pulled as compared to a lighter object. Basically, due to the property of inertia, a body resists change in its motion.

In the given situation, the books are heavier as compared to the paper. A small force would pull out the paper but books being heavy would not move easily. Thus, a paper placed in between two books can be quickly pulled out without moving the books. correct option is d.

Low pH means the solution is acidic; if the solution is acidic, that means that there are hydronium ions in solution (H3O+). For example, hydrochloric acid dissolves into H+ ions and Cl- ions, and the H+ ions rreact with water like this:
H+ + H2O --> H3O+

If you want to get mathematical, pH is defined as the negative log of the concentration of hydronium ions.
Thus, if there are a lot of hydronium ions, the solution will have a low, or acidic, pH. Hope this helps^-^

Answer: 0.011 moles

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP and contains avogadro's number of particles.

To calculate the moles, we use the equation:

given mass = 0.71 g

Molar mass= 63.5 g

The number of moles is 0.011 moles.

0.25 g = 0.00926 Moles
Have a nice day!

0.25 g al should equal around 0.009265594867125 moles
