Sodium and chlorine
Bonds stay together by electrons that travel on the atoms combined, holding the atoms together.
You can form compounds with ionic bonds, or covalent bonds. Example 1: Salts are bonded together with ionic bonds, such as NaCl or CuCl2. When compounds have ionic bonds it is the electrostatic force between the atoms that bonds them together. Example 2: Inorganic/organic molecules are mostly bonded together with covalent bonding. this means that the atoms share pairs of electrons with each other, and there is a equilibrium between the attractive and repulsive forces between the atoms. CO2, EtOH, H2O all have covalent bonds "holding" the molecule together
That would be a heterogeneous mixture.
Amino acids are chemically combined by the formation of peptide bonds.
Ionic bonds are formed between any metal and non metal combination. Whenever there is a positively charged ion and a negatively charged ion, an ionic bond is formed.
They are atoms of the same element. They are packed together because the bonds between them are strong thus forming a solid
everything is matter. compound: substance made up of atleast two different kinds of atoms joined together by chemical bonds. ie H2O. Molecules: two or more atoms of the same element joined together by chemical bonds ie. O2 or Cl2. mixtures: a combination of two or more compounds combined together without chemical bonds that can be separated by means of physical separation. ie sea water element: a single atom that has not been combined with anything else. ie. 1 hyrogen atom. hope this is what you ment:)
Something that chemical bonds can hold together is....
The intermolecular bonds between water molecules are hydrogen bonds.
I think you mean IONS. Elements that form IONS by losing or gaining electrons, form IONIC bonds. These form when a metal reacts with a non-metal.
Hydrogen bonds hold the DNA bases together. There are three bonds between Guanine and Cytosine, and two bonds between Adenine and Thymine.
Are you thinking of covalent bonds? Covalent bonds work to share electrons between two elements so that each may fill their valence shells/orbitals.
