Question

Describe one chemical property of Group 1 metals that results from the atoms of each metal having only one valence electron.

Answer 1

Their ability to lose that electron easily. This property is electronegativity. Once that electron is taken away, the atom becomes an ion with a charge of +1. The ion would be much more stable than the atom, because once the electron is lost, the shell underneath will already have 8 electrons that resembles the configuration of a noble gas.
