If the atom has more electrons than protons, then yes it is an ion.
A neutral atom of a chemical element has a constant number of protons and electrons; loss or gain of electrons transform this atom in an ion.After the change of the number of protons the identity of the atom is lost.
Ions are formed when electrons are transferred among atoms (gained or lost). The charge is determined by the inequal number of protons and electrons. A negatively-charged atom (more electrons than protons) is called an "anion." A positively-charged atom (fewer electrons than protons) is called a "cation." The electrons are located outside the nucleus, while the protons are inside the nucleus. Thus electrons are the charged particles being transferred from one atom to another and not the protons.
Most atoms are electrically balanced because they have the same number of protons, which have a charge of +1, and electrons, which have a charge of -1. However electrons can be lost or gained. When they are, the atom has a different number of protons to electrons so it becomes charged. Example. An uncharged atom of oxygen has 8 protons and 8 electrons. Sometimes it gains two electrons. This means that it has 8 protons but 10 electrons. +8 -10 = -2. therefore the charged atom of oxygen has a charge of -2.
An atom with no electric charge will be called a neutral atom. In a neutral atom, there is a balance of charges, and the number of protons will be equal to the number of electrons. It's really that simple. Compare this to atoms that have an imbalance of charges. These atoms are called ions.
isotope?
The number of electrons should equal the number of protons, otherwise you have an ion.

An atom has three charges: protons which are +, electrons which are - and neutrons which have neither. They balance each other out. If electrons are lost, the atom now has more protons and the atom becomes positive.
the excess protons pull harder on the fewer neutrons
Often there are the same number of electrons as there are protons. Exceptions to this are called ions, which have gained or lost an electron (can't be a proton lost or gained, that would change the element).
That depends on the number of protons. It also depends whether the atom has gained or lost electrons to form an ion. Carbon is element number 6; it has 6 protons and 6 electrons. Lead is element number 82; it has 82 protons and 82 electrons.
An atom that has gained or lost an electron and is therefore no longer electrically neutral is generically called an ion.Specifically, an atom/ion that has lost one or more electrons (and is therefore positively charged) would be called a cationand an atom/ion that has gained one or more electrons (and is therefore negatively charged) would be called an anion.There is also a state of matter where all the electrons are stripped from atoms, this is called a plasma.The loss or gaining of an electron does not affect the number of protons in the nucleus.The number of protons and neutrons in the atom's nucleus are fixed for the atom from the moment of its creation unless it undergoes radioactive decay.For an atom, the number of protons determines what element the atom comprises and the variation in the number of neutrons forms the isotopes for that element.
An electron or electrons is/are lost or gained to produce an ion. An atom with the same number of electrons as protons is a neutral atom. If the proton count and electron count do not match, that atom is electrically "imbalanced" and is an ion.
For each element, the number of protons it has is equal to the number of electrons it has. However, if the atom has a different amount of electrons, then the charge will tell you that. If the charge is negative (-) then that says how many electrons the atom has gained, and if the charge is positive (+) then that says how many electrons the atom has lost.
An atom that has gained or lost electrons is called an ion. An atom that has gained one or more electrons becomes a negatively charged ion called an anion. An atom that has lost one or more electrons becomes a positively charged ion called a cation.
