The answer might be terrain, if that helps.
Hydrogen ion<span>, strictly, the nucleus of a hydrogen atom separated from its accompanying electron. The hydrogen nucleus is made up of a particle carrying a unit positive electric charge, called a </span>proton<span>. The isolated hydrogen </span>ion<span>, represented by the symbol H </span>+<span>, is therefore customarily used to represent a </span>proton<span>.</span>
One system must have higher kinetic energy than the other system
Answer:
3
Explanation:
Since the atom has three electrons, it has a -3 electrical charge. Since atoms are neutral, 3 protons are needed to get the charge back to 0.
