Metallic ions are best described as: anions giving up electrons and attracting each other anions together in a sea of electrons cations grabbing electrons from anions cations together in a sea of electrons

cations together in a sea of electrons

Explanation:

Metallic bonding is the type of chemical bonding occurs between the atoms of a metals. In this type of bonding arises due to electrostatic interaction between the electron cloud of de-localized electrons with positively charges metal ions called as cations.

These de-localized electrons are the valence electrons of metal atoms which are shared between them.

In ionic bonding , the cations are attracted to anions where cations are formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
