Read the given expression. X = number of protons − number of core electrons Which of the following explains the identity of X an
shepuryov [24]

<u>Answer: </u>The correct statement is X is the effective nuclear charge, and it increases across a period.

<u>Explanation:</u>

We are given that:

X = number of protons − number of core electrons

Effective nuclear charge is defined as the actual nuclear charge (Z = number of protons) minus the screening effect caused by the electrons present between nucleus and valence electrons. These electrons are the core electrons.

The formula used for the calculation of effective nuclear charge given by Slater is:

Z^*=Z-\sigma

where,

Z^* = effective nuclear charge

Z = atomic number or actual nuclear charge or number of protons

\sigma = Screening constant

The effective nuclear charge increases as we go from left to right in a period because nuclear charge increases with no effective increase in screening constant.

Hence, the correct answer is X is the effective nuclear charge, and it increases across a period.

Answer:

Amplitude ----> C.) The distance from a crest or trough to the rest position on the horizontal axis

Crest ---> A.) The highest point of a wave

Destructive interference ---> E.) A situation in which the crest of one wave and the trough of another overlap, resulting in a wave that has a smaller amplitude than the original waves

Sound Wave ---> B.) A vibration transmitted through an elastic medium, such as a gas, liquid, or solid

Trough ---> D.) The lowest point of a wave
