Answer 2

Ne is isoelectronic with hydroxide ion.

• The species which contain the same number of electrons are called isoelectronic species.
• The formula of hydroxide ion is $OH^-$.
• The number of electrons in an Oxygen atom is 8 and in H is 1. Hence the total number of electrons in hydroxide ion is 8+1+1=10.
• Hence the element Ne has 10 electrons and it is isoelectronic with hydroxide ion.
