Question

when metals react they ________________ (gain/lose) electrons. as you go down any group containing metals, it becomes easier to lose electrons because they are further away from the attractive force of the positive nucleus.

Answer 1

When metals react they lose electrons.

Step-by-step explanation:

An ion is defined as a molecule or atom made up of a different number of electrons and protons. This makes the electric charge of the molecule net, not neutral.

In other words, an ion is a molecule or atom that has a positive or negative electric charge, making it an atom whose electric charge is not neutral.

The characteristic property of a metallic atom is to lose one or more of its electrons to form a positive ion. That is, metals lose electrons and acquire a net positive charge, which is why they are electropositive.
