What shows the relative number of atoms of each element in a compound.?

Answer 1

It is important to know the relative number of atoms of each element in a compound for the chemical composition.

Answer 2

Add the subscripts (little numbers next to each chemical symbol) together.

For example, to find out the # of atoms in a glucose molecule, or C6H12O6, you would add up the subscripts: 6 carbon + 12 hydrogen + 6 oxygen = 24 atoms total.

Answer 3

In a molecular formula, the subscripts show the quantities of each element in a compound.

for example, in the ionic compound (NH4)3PO4 there are 3 (1*3) molecules of nitrogen (N), 12 (4*3) molecules of Hydrogen (H), one molecule of phosphorus (P), and 4 molecules of Oxygen (O).

Answer 4

The atomic number of an atom is equivalent to the amount of protons in its nucleus. Look up the atom you are researching on the Periodic Table and you should see it's atomic number in the upper left corner of its box.

Answer 5

Subscripts.

C6H12O6

This formula of glucose shows us that there are...,

6 atoms of carbon

===================

Answer 6

The subscripts that follow the symbol of each element in a molecule show the number of atoms of each element in the molecule. If there is no subscript, the number is understood to be 1.

H2O - two atoms of hydrogen and one atom of oxygen

CO2 - one atom of carbon and two atoms of oxygen

C6H12O6 - six atoms of carbon, twelve atoms of hydrogen, and six atoms of oxygen

Answer 7

Valence electrons are electrons in the outer shell of an atom. a quick way to do it is to look at the atomic number of the element and subtract 2 from that.
