The group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
An atom with a charge is called an ion. If the atom gains electrons, it becomes a negative ion (anion), while if it loses electrons, it becomes a positive ion (cation).
If the atom loses electrons, the atom becomes positively charged because the number of positively charged protons.
An atom that has gained an electron becomes a negatively charged ion.
Ion
When the number of electrons changes, the atom becomes an ion. An atom becomes a positively charged ion (cation) when it loses electrons and a negatively charged ion (anion) when it gains electrons.
If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.
An atom with a charge is called an ion. If the atom gains electrons, it becomes a negative ion (anion), while if it loses electrons, it becomes a positive ion (cation).
yes...on gaining an electron, the atom becomes an anion i.e. negatively charged ion.
an atom that gains an electron becomes a negative ion, called an anion.
An atom that loses electrons becomes a positively charged ion called a cation. An atom that gains electrons becomes a negatively charged ion called an anion.
When an atom loses electrons, it becomes a positively charged ion called a cation. When an atom gains electrons, it becomes a negatively charged ion called an anion.
When an atom becomes ionized, it gains or loses electrons (usually one).
An atom can become an ion by either gaining or losing electrons. If it gains electrons, it becomes an anion. If it loses electrons, it becomes a cation. An ion is merely an atom with a charge, either positive or negative.
A charged atom is an ion. An atom that has lost one or more electrons becomes a positively charged ion called a cation. An atom that has gained one or more electrons becomes a negatively charged ion called an anion.
Positive ion
If the atom loses electrons, the atom becomes positively charged because the number of positively charged protons.
When an electron is transferred from a sodium atom to a chlorine atom, the chlorine atom becomes a negatively charged ion because it gains one electron. This negatively charged ion is known as chloride ion.
