An ion. If electrons are in excess over proton then it is negative ion. And if less then positive ion
The number of protons is a specific characteristic of an atom; if the number of protons is other the element is other.
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.
The number of electrons should equal the number of protons, otherwise you have an ion.
protons and electrons are identical in number in an atom
The number of electrons should = the number of protons.
protons, because the protons are positive and the electrons are negative so to have a neutral atom the protons and electrons must be balanced
An ion
In a neutral atom the number of electrons is equal to the number of protons; and the number of protons is the label of a chemical element.
Because it hs a different number of protons and electrons
The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.
No. The number of protons and electrons is the same, resulting in a neutral atom (magnesium in this case). In order to be an ion the number of protons and electrons must be different.
The name is ion.
