We’re being asked to determine the formula of a monoatomic ion and determine chemical symbol of the noble gas this ion is isoelectronic with.
The monoatomic ion has charge of +2:
• positively charged ions are called cations
• Therefore, the ion is a cation.
Let’s determine the chemical symbol of the noble gas this cation is isoelectronic with.
Isoelectronic means that two species have the same number of electrons.
The cation has an electronic configuration of 1s22s22p6:
A monatomic ion with a charge of +2 has an electronic configuration of 1s 22s22p6.
This ion is (n) ___________.
What is the chemical symbol of the noble gas this ion is isoelectronic with?
What is the formula of the ion?
