Explanation:

In an atom number of electrons and protons are equal. it is an electrically neutral specie.

In an ion, the number of electrons and protons are not equal. There are two types of an ion :

Cation: When the number of protons are greater than number of electrons. These ions have a positive charge.
Anion : When the number of electrons are greater than number of protons. These ions have a negative charge.

Hence, if an atom is considered as an ion, then it will have an unequal number of protons and electrons.

Explaining How Momentum Can Cause

Ghella [55]

Answer:

The astronaut can throw the hammer in a direction away from the space station. While he is holding the hammer, the total momentum of the astronaut and hammer is 0 kg • m/s. According to the law of conservation of momentum, the total momentum after he throws the hammer must still be 0 kg • m/s. In order for momentum to be conserved, the astronaut will have to move in the opposite direction of the hammer, which will be toward the space station.
