Usually, an atom has the same number of protons as electrons, but when the number of electrons is changed, the atom is considered ionic. An atom that has lost an electron is called an anion, and an atom that has gained an electron is called a cation. One example of a cation is a potassium ion, or K+, and one example of an anion is chloride,(a chlorine ion) or Cl-
A cation is a type of an ion, or a charged atom. An atom is the main module. They have the same number of protons and electrons. An ion has a different number between the two. A cation is just an atom with fewer electrons than protons.
The size of an anion is larger than its parent atom because anions are formed due to the gain of electrons. When the electrons increase, there are still the same number of protons. The attractive force is thus reduced as there are the same number of protons attracting an increased number of electrons. This causes the electrons to not be bound as tightly to the nucleus resulting in an increase in size. In other words, anions have one or more extra electrons that contribute to the size of the atom. These extra electrons increase its size and make it larger than the neutral atom.
the same number of electrons needed to fill their octet, the same number of valence electrons,
An atom that has lost or gained electrons is known generally as an ion. More specifically, an atom that has lost electrons becomes a cation. It has a positive charge. An atom that has gained electrons becomes an anion. An anion has a negative charge.

If the atom is atomically neutral (meaning that it does not hold a charge and it's not a cation or an anion), then the number of electrons and protons in an atom will be the same. If they do hold a charge (say if it is an anion), then it would have an extra electron. If it was positively charged, then an electron would be lost.
the number of electrons in the outer shell .. for metals its less than 4 .. for non metals its more than 4 .. for semi its 4
The weights of atoms are based primarily on the number of protons and neutrons in an atom. This is because protons and neutrons are many times the weight of electrons. Since electrons contribute a minuscule amount, even on the atomic level, to the mass of the atom, the mass of the atom is taken to be the same whether it is a anion of a cation. Remember, it is the number of electrons in an atom that determines whether it is an anion, cation, or a neutral atom. If there is a different number of neutrons it is called an isotope, and will have a different mass. If it has a different number of protons, it is a different atom and will have a different mass.

All electrons are the same. A negatively charged atom would be an anion.
Oxygen gains two electrons (is reduced, "Reduction is gain") to form the O2- anion this gives oxygen an outer shell the same as neon, and completes the "octet" in its outermost shell of electrons.
are you in Chem 115 at WVU? i have the same question for hw
For example calcium and magnesium.
