Question

Why do metals have a positive charge?

Because they lose protons.
Because they gain protons.
Because they gain electrons.
Because they lose electrons.

Answer 1

D. Because they lose electrons

Step-by-step explanation:

In neutral state the numbers of proton (+) = numbers of electrons (-)

if there are less electrons, there will be more protons than electrons => positive charge

if there are more electrons, there will be more electrons than protons => negative charge
