These chemical bonds are ionic, covalent or metallic.
chemical A+ :D
Mostly hydrogen bonds.
a hydrogen bond holds two atoms of hydrogen together.
Covalent bonds hold all these atoms together with the central atoms here the two phosphorous atoms.
In sodium metal the atoms are held together by metallic bonds.
The bond in water is covalent.
double covalent bonds
quite simply, bonds. The strength of these bonds depends on the type of element or compound that forms the solid. These 'particles' you refer to are best known as 'atoms' and the atoms that form a solid are held together by these bonds.
Two types of chemical bonds are very important: ionic and covalent.
Go to the question box and type in What holds atoms in compounds together? I posted the answer there, sorry for the wait.
The nitrogen molecule consists of two atoms of nitrogen held together by "covalent" bonds.
The hydrogen and oxygen are held together by polar covalent bonds.
