。☆✼★ ━━━━━━━━━━━━━━━  ☾

As you move across the period, the atomic radii decreases.

This is because of an increase in the number of protons (and electrons) and therefore, an increase in the nuclear charge.

Answer:

The atomic radii decreases from left (sodium) to right (Argon).

Explanation:

The number of  positive protons in the nucleus increases so the pull on the electrons increases and this decreases the radius.

The ion with the smallest diameter is ________. The ion with the smallest diameter is ________. Be2 Sr2 Ca2 Ba2 Mg2
mart [117]

Answer:

Be2^+

Explanation:

Ionic diameter increases down the group. This implies that Be2^+ will have the smallest diameter.

This extremely small diameter makes Be2^+ to differ considerably from other ions of group 2 elements.

For instance, the compounds of beryllium are mostly covalent in nature.

Hello please please help me​

Answer:

            Option-A is the correct answer

Explanation:

Lithium belong to group 1 metals. Hence, it can loose one electron to form lithium ion i.e. Li⁺¹ or Li⁺

While, Nitrogen is non-metal and hence has the ability to gain the electron lost by lithium metal. Furthermore, Nitrogen can gain maximum 3 electrons to acheive noble gas configuration. Hence, three Li atoms will loose their electrons and Nitrogen will gain those three electrons to form nitride ion i.e. N³⁻.
