What is a property of most metals?
(1) they tend to gain electrons easily when bonding.
(2) they tend to lose electrons easily when bonding.
(3) they are poor conductors of heat.
(4) they are poor conductors of electricity.

(2) They tend to lose electrons easily when bonding is the correct answer.

All metals have either one, two, or three valence electrons. Therefore, they tend to lose these valence electrons in order to have eight valence electrons like noble gases do.

Hope this helps~
