Oxidized.
Oxidation involves a loss of electrons.
The answer above in a general context is wrong I'm afraid - If an atom loses an electron it becomes an ion and the same if it gains one - and electrically charged particle.
A molecule that gives up an electron becomes
Electrons carry a single unit of negative charge. Therefore, a molecule that loses an electron becomes an ion with a 1+ charge.
a positive ion
a cation
D OXIDATION-REDUCTION REACTION
An electron is a part of a atom, and an atom is part of a molecule, molecules make up a cell. So a cell is biggest.
Yes. It becomes a cation (a positive ion). Yes. Each positively charged proton in the nucleus must be cancelled out by a negatively charged electron, or else any noncancelled proton's positive charge will give its atom a positive charge. Likewise the atom that gains the lost electron will have more negatives than positives and will gain a negative charge.
purley ionic bonds do not occour because the atoms that gives up an electron in such a bond
When two atoms come together and form a bond, they can do so by either sharing electrons or by taking/donating them. When they share electrons, electron density is smeared out between the atoms. (You can think about an electron bouncing back and fourth between the atoms.) When an ionic bond forms, one atom gives up one electron to another. When an atom gives up an electron, it becomes positive, and when an atom gains an electron it becomes negative. When this happens, you end up with one positive atom and one negative atom. Just like when opposite ends of a magnet attract one another, so do the positive and negative atoms. These opposites attract and stick together.
true
Well if a atom loses or gains an electron it becomes an ion - a positively of negatively charged atom.
oxidation-reduction reaction
when a neutral atom (same number of electrons and protons) loses an electron, it is charged positively. when a neutral atom gains an electron, it is charged negatively. In this state, it is known as an ion.

An electron is a part of a atom, and an atom is part of a molecule, molecules make up a cell. So a cell is biggest.
An oxygen atom gains 2 electrons when it becomes an ion because it wants a full valence shell (as in, its outer energy level is trying to reach 8 electrons).

Yes. It becomes a cation (a positive ion). Yes. Each positively charged proton in the nucleus must be cancelled out by a negatively charged electron, or else any noncancelled proton's positive charge will give its atom a positive charge. Likewise the atom that gains the lost electron will have more negatives than positives and will gain a negative charge.
A sodium atom becomes a sodium ion, when a neutron is added to the nucleus.
Supposedly one of the down quarks of the neutron becomes an up; thus the neutron becomes a proton and an electron (and a neutrino) are emitted.
