Ions and Valence Electrons

Organize these options into the right categories

Groups:

(a) Atom

,

(b) Ion

• uneven # of protons and electrons

• even number of protons and electrons

• positive charge balances out negative charge

• overall positive or negative charge

• protons = electrons

• positive charge does not balance out the negative charge

• protons ≠ electrons

• neutral charge

• do not have a charge

• have a charge

All elements start out as ​ (a)   atoms. This means their number of protons and ​ (b)   is equal. When they gain or lose electrons, they become ​ (c)   ions and are no longer neutral. There are 2 types of ions: ​ (d)   which have a positive charge and ​ (e)   which have a negative charge.

• neutral
• electrons
• charged
• cations
• anions
• neutrons
• dipoles
• atomions
• chargion
