What script number tells of the preceding element in the compound?

The subscript number after the preceding element in a compound tells how many atoms of that element are in a molecule or formula unit of the compound. For example, the molecular formula for water, H2O indicates that there are 2 atoms of hydrogen and 1 atom of oxygen in one molecule of water. The formula unit for the ionic compound calcium chloride, CaCl2, indicates that there are 1 calcium ion and 2 chloride ions in a formula unit of calcium chloride.

What is the name of the compound with the formula MgI2?
Magnesium bromide pentahydrate. (MgBr2.5H2O) NB 'mgbr25h2o'. is incorrectly written. When writing chemical formula a one-letter symbol is always a capital letter .e.g. 'H' hydrogen and 'O' oxygen. A two-letter symbol is always written ; first letter is a capital letter and the second letter is small/lower case. e.g. 'Mg' Magnesium and 'Br' Bromine. Prefixed numbers (Molar ratios) are full script. post script numbers indicating the number of a given atom are written subscript ; unfortunately I cannot show it on Answers. A 'Full stop/Period' is always placed between the given compound and the hydrate number.

How does an isotope differ from a normal atom?
When an atom is of the same atomic number, atomic mass, etc. to the one on the periodic table (Lets use Boron for example) Then B is the regular atom. But if you change the number of nuetrons (from 6-to-7 or whatever number) ; because the number of protons never changes; you will get a different atomic mass, so an isotope is the atom with a different atomic mass. You write an isotope atom with the elements symbol and to the left of it you script (In the top left corner really small like an exponent) the new atomic mass. So in this case B would now be 12B. (except scripted, but I sadfully forgot how to do that on a computer....)
If you have 0.50 mole of Ca how many atoms are present?
What compound? Please copy your homework questions completely. How else can we help you cheat?To find the number of moles of oxygen (or any other element), multiply the number of atoms present on the molecule (in subscript) by the number of molecules present in the reaction (in standard script to the left of the molecule)In this case:2 H2 + O2 --> 2 H2OOn the reactant side (to the left of the arrow), there are 4 moles of hydrogen present because we have inserted 2 moles of diatomic hydrogen (multiply the subscript 2 by the standard script 2 to the left of the molecule). We can calculate that there are 2 moles of oxygen present because we have inserted one mole of diatomic oxygen. On the products side (the right side of the arrow) we produced 2 moles of water (indicated by the standard script 2 to the left of the molecule) Each molecule of water contains 2 molecules (2 moles) of hydrogen and one molecule (one mole) of oxygen. Thus, we have a balanced equation because this gives us 4 moles of hydrogen and 2 moles of oxygen, just like we had on the reactant side.The multipliers in standard script to the left of the molecule gives us the molar ratio. 2 moles of diatomic hydrogen react with 1 mole of diatomic oxygen to produce 2 moles of water. Thus, if we were to burn .5 moles of diatomic hydrogen in excess oxygen, we would produce .5 moles of water. This is because, by looking at our chemical equation, we see that the molar ratio of diatomic hydrogen to water is 2:2 (or 1:1). We would have .25 moles of oxygen because the ratio of hydrogen to oxygen is 4:2 (or 2:1).Were this the question on your homework, the answer would be ".25 moles"
