As an atom’s radius increases, 1. its ionization energy increases. 2. its ionizations energy increases or decreases depending on

Serhud [2]

Answer:

The correct option is: 4. its ionization energy decreases

Explanation:

Ionization energy refers to the energy required to pull a valence electron completely from the valence shell of a gaseous atom.

Now, in the periodic table of chemical elements, as we down a group, the atomic radius increases, so the effective nuclear charge experienced by the valence electron decreases. Therefore, the ionization energy decreases, down the group.

As we across a period, the atomic radius usually decreases, so the effective nuclear charge experienced by the valence electron increases. Therefore, usually the ionization energy increases, across the period.

Therefore, as the atomic radius increases, the effective nuclear charge experienced by the valence electron decreases and thus the ionization energy also decreases.

A hunter fires a rifle while seated with the butt of the gun resting against their shoulder. If the forward momentum is the same

Debora [2.8K]

Answer:

Because the bullet is smaller and has a sharp/pointy tip.

Explanation:

The bullet kinda puts the majority of kinetic energy in a small are, whereas the gun butt kinda spreads the energy evenly amongst a larger surface. If more explanation is needed add comment.

A perceived increase in the volume of sound is best explained by ________.

tatiyna

Answer:

A. an increase in the height of the sound wave

Explanation:

Volume of the sound is measured by its intensity

So here we know that

intensity is directly depends on the square of the amplitude of the sound wave

so here as intensity depends on the loudness of the sound given as

$L = 10 Log(\frac{I}{I_o})$
