What atomic number 18 bonds
Elements ar the simplest substances that exist on earth. Each member is made up of just one type of atom, comm nevertheless joined to other atoms of the same element by bonds. These forums molecules such as chlorine (cl2)
Compounds ar formed when different elements chemically react and form bonds with each other. Some compounds like, like peeing (H2O) have small, simple structures with just a few atoms bonded to fillher. Others compounds Bonds adopt the electrons in the outermost shells of atoms ends like DnA1 have large tangled structures containing thousands or even millions of bonded atoms.
Why do atoms form bonds?
The atoms of majestic gasses have completely full outer shells and so are stable this makes the noble gasses very unreactive and so they do not usually form bonds. The atoms of other elements have partial out electron shells and so are unstable. By forming bonds, the atoms of these elements are able to have filled outer shells and come unstable.
What are they types of bonding?
Different types of bonds are formed depending on the types of atoms involved.
garret bonding
* Occurs between metal and non-metal atoms.




Covalent bonding
* -------------------------------------------------
Occurs between non-metals atoms only
An ion is an atom or group of atoms have has electrical charge, all positive or negative. Atoms have an equal number of protons and electrons and so do not have an general charge.
Atoms with incomplete outer electron shells are unstable. By either gathering or losing electrons, atoms can obtain full outer electron shells and release stable.
-------------------------------------------------
When this happens atoms have an unequal number of protons and electrons and so have an overall charge. This is how atoms become ions. How does an atom become a positive or negative ion?
What is Ionic bonding?
Compounds that contain ions are called noggin compounds. These compounds are usually formed by a...If you want to get a full essay, order it on our website: Ordercustompaper.com
