g Chemical species are said to be isoelectronic if they have the same Lewis structure (regardless of charge). In order to achieve an electron configuration that is isoelectric with a noble gas, nonmetals tend to .

Accept electrons

Explanation:

Non metals are found towards the right hand side of the periodic table. They usually possess more valence electrons than metals.

Hence, they do not give out electrons as metals do in order to become isoelectronic with the noble gases because this will cost a lot of energy. Rather, they accept electrons in order to become isoelectronic with noble gases.

Isoelectronic means that the both species have the same number of electrons. In accepting electrons, nonmetals form negative charges.

i wish i could but this one is weird give me abc and i can solve it.
