A charge.
Atoms are uncharged because for every electron (-ve) there is a proton in the nucleus with a positive (+ve) charge. These cancel each other out.
The charge comes from having an unequal number of electrons and protons. The number of protons always stays the same. That is what tells you what atom it is. Atoms can lose or gain an electron though. If it gains an electron then it becomes negatively charged as it has 1 more electron than protons, if it loses an electron then it becomes positively charged because it has 1 more proton than electrons.
A negative ion (anion) has more electrons than protons. The electrical charge is negative.
A positive ion has an excess of protons over electrons leaving a net positive charge on the species.
An anion is an atom with an excess of electrons. Examples: Cl-, SO42-.
Lost their electron shells.
There is only one type of electron
The loss or gain of electrons transform an atom in an ion.
An atom with a charge (either positive or negative) is called an "ion." An ion with a positive charge is called a "cation" and an ion with a negative charge is called an "anion ."
'Fluoride atom'. ???? The fluorine ATOM is 'F' The fluorine molecule is 'F2'. The Fluoride ION is 'F^-' NB When an atom becomes a charged species, it is no longer an atom , but an ION. The suffix '--ide' indicates it is an ion, not an atom. So 'Fluoride atom' is a nonsense. It is either 'Fluoride ion' or Fluorine atom'.
Ion
A neutrally charged atom is just called an atom. This is when the atom's number of electrons is equal to its number of protons, canceling out all far-field electromagnetic effects. If the atom has a net charge, it is then called an ion.
what does an atom have in common with an ion?
what does an atom have in common with an ion?
An ion is a positively or negatively charged atom or molecule.
An ion is an atom with a positive or negative charge.
ion
The loss or gain of electrons transform an atom in an ion.
An atom is called an ion if there is a charge on it - positive or negative.
If the number of protons and neutrons are the same, its an atom, if not its an ion
A ion is an electrically charged atom, positive or negative.
When an atom gets charged it is called ion.

An atom with a charge (either positive or negative) is called an "ion." An ion with a positive charge is called a "cation" and an ion with a negative charge is called an "anion ."
