Lithium has an atomic number of 3.
Lithium's Atomic Mass is 6.9.
The atomic number refers to the number of protons in the nucleus of an element. As elements are electronically neutral the atomic number also refers to the number of electrons in a normal atom of that element.
The atomic mass is an average and can be said to refer to the combined mass of the protons and neutrons in the nucleus (protons and neutrons both having an atomic mass of 1).
Lithium, therefore, has 3 protons, 3 electrons and 4 neutrons (on average).
Lithium is in group 1 which means it is an alkali metal.
Being in group 1 also means that Lithium has only one electron in its outer shell.
Alkali metals are highly reactive because they only need to get rid of one electron in an ionic bond in order to have a full outer shell. As one travels down the Periodic Table the number of electron shells increase and so too does the distance an outer electron is from the nucleus. This increase in distance means the nucleus' hold on the outer electrons is diminished and thus the element will give up its outer electrons easier. This, in turn makes the alkali metals further down the table more reactive than those higher up.
Alkali metals are so called because when they react with water they form an alkali. Lithium reacting with water will form lithium hydroxide.
Lithium is a metal with a relatively low density that floats on water and will react violently with water and discolour rapidly in air.

The element with a proton number of 15 is Phosphorus; P
protons, no. of protons is equal to the atomic number of an element.
The element with one proton per atom is hydrogen.
Proton number, which is an element's atomic number, identifies an element. Each element has a unique atomic number (number of protons).
The number of PROTONs and the number of ELECTRONs are always equal in a neutral atom. Therefore an element with one PROTON will have one ELECTRON and that element will be called Hydrogen.
