A particle that contains 11 protons, 12 neutrons and 10 electrons is probably a
neutral non-metal
metallic ion
non-metallic ion
neutral metal

Explanation

Given:

n(P) = 11

n(N) = 12

n(e-) = 10

\(^{23}_{11}\) X \(^+\) ⇒ The positive sign shows that it is a metallic ion because all metals are positively charged.
