What is a combination of element symbols that shows the ratio of elements in a compound?

Answer 1

It use the symbols as alphabetical characters for element names for examples: C for Carbon, Cu for copper (Cuprum in latin)

And in the lower left of the symbol is atomic number, for C it is 6: 6C

in the upper left of the symbol is the mass number, for C it is 12 : 12C

(or with another isotope, 13)

Then the full nomination: 612C (write 6, and 12 one column aligned)

(answer)

My chemistry book states that its a Chemical Formula, "a shorthand representation of the composition of a substance using atomic symbols and numerical subscripts"

Answer 2

In the formula for a compound, you will see atomic symbols representing individual elements, and if needed, you will see subscripts that represent the number of those atoms required for that bonding scenario. Sodium chloride, for example is NaCl. You see the symbol for sodium followed by the symbol for chlorine. No subscripts are needed because sodium and chlorine combine in a 1-1 ratio. However, in aluminum oxide, the formula is Al2O3. Two aluminums are required for every three oxygens. The subscripts reflect that bonding ratio.

Answer 3

Yes, it is the chemical formula of a compound.

Answer 4

mass number over atomic number next to the element symbol

Answer 5

The notation that shows what elements are present in a compound and shows the ratio of these is called the chemical formula

Answer 6

This representation is called chemical formula.

Answer 7

A chemical formula

Answer 8

a chemical formula

Answer 9

subscripts

Answer 10

Subscript
