Such an atom has a net electric charge, and is known as an ion.
The nucleus of an atom has both electrons and neutrons. An atom that has a positive charge means that the atom has fewer electrons than it has protons.
Electrons. Electrons carry a negative charge so when one is removed from the atom the atom gains a net positive charge.
More the number of shells in an atom, more away will be the electrons from the nucleus. Hence, weaker will be the attraction between nucleus and outermost electrons. So atom with more shells will let go their electrons easier than atoms with fewer shells.
An isotope has extra or fewer neutrons in the nucleus than the average number for that element. This may or may not result in a radioactive isotope. An ion has extra or fewer electrons orbiting the nucleus. This usually increases the chemical reactivity.

The neutral atom of sodium has 11 electrons.
Such an atom has a net electric charge, and is known as an ion.
An atom is charged when it has more or fewer electrons than in its natural state. This is also called an Ion. Ions can be positively charged (more electrons) or negatively charged (fewer electrons).See wikipedia for a thorough dissertation
The ion is positively charged because it has fewer electrons than the atom.
The nucleus of an atom has both electrons and neutrons. An atom that has a positive charge means that the atom has fewer electrons than it has protons.
Electrons. Electrons carry a negative charge so when one is removed from the atom the atom gains a net positive charge.
More electrons = negatively charged = anion Less electrons = positively charged = cation
More the number of shells in an atom, more away will be the electrons from the nucleus. Hence, weaker will be the attraction between nucleus and outermost electrons. So atom with more shells will let go their electrons easier than atoms with fewer shells.
An isotope has extra or fewer neutrons in the nucleus than the average number for that element. This may or may not result in a radioactive isotope. An ion has extra or fewer electrons orbiting the nucleus. This usually increases the chemical reactivity.
It is a Cation, an ion with fewer electrons than protons, giving it a positive charge
An atom that has fewer than 8 valence electrons is more reactive, or more likely to form bonds, than an atom with 8 valence electron. Atoms bond by gaining, losing, or sharing electrons in order to have a filled outermost energy level with 8 valence electrons.
