Ions are electrically charged particles formed when atoms lose or gain electrons. This loss or gain leaves a complete highest energy level, so the electronic structure of an ion is the same as that of a noble gas - such as a helium, neon or argon.
Metal atoms and non-metal atoms go in opposite directions when they ionise:
- Metal atoms lose the electron, or electrons, in their highest energy level and become positively charged ions.
- Non-metal atoms gain an electron, or electrons, from another atom to become negatively charged ions.

When iron reacts with oxygen to form rust each iron atom losses or gains irons?
The iron atom doesn't gain or loss "irons". The question does not make sense.
The process by which the nucleus of an atom changes so that a new element forms is called?
transmutation
Which process changes a chlorine atom into a chloride ion?
This is a reduction reaction, because it gains an electron.
What changes the charge of the atom?
what changes the charge of the atom
What is the process called that changes a neutral atom into an electrically charged atom?
Ionization. An electrically charged atom is called an ion. Positively charged ions are called cations, and negatively charged atoms are called anions.
When an atom gains or looses electrons what to the charge of atom?
When an atoms gains an electron the atom changes into a negative ion and when an atom loses an electron the atom changes into a positive ion.
What is the process by which the nucleus of an atom changes so that a new element is formed?
Most likely this is some sort of radioactive decay.
What is the ability of a substance to undergo or resist chemical changes?
Chemical Reactivity :)
The mass number of an atom changes if its number of what changes?
neutrons
The process by which an atom becomes charged?
The process in which an atom becomes charged is IONIZATION.
How does a carbon atom in the air become part of a starch atom in a carrot?
A carbon atom would become a starch molecule in a root hair by a chemical reaction known as photosynthesis. Photosynthesis is a process that changes light gained from the sun into energy.
What is the process of an atom?
Nomenclature
