Because of the law of conservation of mass/matter. Matter is neither created nor destroyed in a chemical reaction, but it is rearranged so that the combined mass of the reactants is equal to the combined mass of the products.
The aim of the burning magnesium experiment is to demonstrate the intense, bright white light produced when magnesium metal combusts in air. The experiment is often used to showcase the principle of combustion and the high reactivity of magnesium with oxygen.
Anywhere from 36 to 38, however, this is assuming you are talking about neutral atoms. The variation comes from the different stable isotopes of Magnesium, of which there are three.
Neutrons are the other subatomic particles that make up the magnesium atom. Magnesium has 12 protons, 12 electrons, and typically 12 neutrons in its nucleus, giving it an atomic number of 12.
24, it's the number of protons and neutrons, i.e. the number of sub-atomic particles in the nucleus.
The atomic number of magnesium is 12. The atomic number tells you the number of protons in the nucleus of the magnesium atom, which also corresponds to the number of electrons in a neutral magnesium atom.

Magnesium is in the group 2. 0 is the lowest oxidation number for it.
One mole of MgSO4 contains 6.022 x 10^23 particles, which is known as Avogadro's number. This includes all the atoms of magnesium, sulfur, and oxygen in one mole of MgSO4.
Singl atom has 12 electrons. Oxidation number of it is +2.
Magnesium is a metal element. Atomic mass of it is 24.
The isotopes of magnesium differ in their number of neutrons. Magnesium has three stable isotopes: magnesium-24, magnesium-25, and magnesium-26, with varying numbers of neutrons in their nucleus.
Valency is not a word... but if you want to know the number of valence electrons that Magnesium has, it is 2. Magnesium's atomic number is 12.
