Ionic bond. When atoms gain or lose electrons (negatively-charged particles) they become ions. If an atom gains electrons it becomes a negative ion (an anion, eg Cl-). if an atom lose an electron it becomes a positive ion (a cation, eg Na+). The electrical attraction between oppositely-charged ions (eg Na+ and Cl-) is an ionic bond. See http://www.bbc.co.uk/schools/gcsebitesize/chemistry/classifyingmaterials/ionic_bondingrev5.shtml which includes a simple animation.
An atom that has gained or lost electrons is called an ion. An atom that has gained one or more electrons becomes a negatively charged ion called an anion. An atom that has lost one or more electrons becomes a positively charged ion called a cation.
Atoms: atoms are the elements that cannot be futher divided by chemcal means. They are undivisible and cannot be broken down. They consist of electrons in their oribital shells, protons and neutrons in the nucleus. Atoms are arranged by atomic number on the periodic table of elements. Bonding: Bonding is when two or more atoms are bonded together by electrons to fulfill each other's outer valence shell to become a stable compound/molecule. :)
An atoms size is relative to the number of electrons an atom contains. Atoms with the least number of electrons are the smallest atoms. When atoms have the same number of electrons, the atom with the most protons will have the largest nuclear charge, and therefore be the smallest atom.
the covalent bonds in organic molecules are higher energy bonds than those in water and carbon dioxide.
Molecules Atoms which are elements make up molecules. Protons and electrons make up atoms.
Valence electrons are involved in bonding to other atoms.

Electrons involved in bonding between atoms are valence electrons.
the bond in which electrons are lost or oxygen atoms are gained or hydrogen atoms are lost.
Valence electrons
Generally the core electrons.

Ionic bonds are formed between positively charged atoms (lost electrons) and negatively charged atoms (gained electrons).
Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.
Essentially, pairs of electrons are shared in a covalent bond. Generally, it is greatest when atoms display comparable electronegativity. 2055FCCE-0BFC-F902-5F3E-8A1C92C17B91 1.03.01
Atoms that have lost one or more electrons form an ionic bond with an atom that has gained one of more electrons.
Sulfur ions are sulfur atoms that have gained two electrons.
