WebAug 19, 2024 · 3 Ca atoms. 2 × 1 P atoms. 2 × 4 O atoms. That is, 3 Ca atoms, 2 P atoms, and 8 O atoms. Chemical formula can be used in chemical equations. For example, the reaction of hydrogen gas ( H 2) burning with oxygen gas ( O 2) to form water ( H 2O) is written as: 2H 2 + O 2 → 2H 2O. Exercise 1.4.3. WebH 2 is a molecular formula; it represents a diatomic molecule of hydrogen, consisting of two atoms of the element that are chemically bonded together. The expression 2H, on the other hand, indicates two separate hydrogen atoms that are not combined as a unit. The expression 2H 2 represents two molecules of diatomic hydrogen (Figure 3.3. 3 ).

Earlier symbols for chemical elements stem from classical Latin and Greek vocabulary. For some elements, this is because the material was known in ancient times, while for others, the name is a more recent invention. For example, Pb is the symbol for lead (plumbum in Latin); Hg is the symbol for mercury (hydrargyrum in Greek); and He is the symbol for helium (a new Latin name) because helium was not known in ancient Roman times.
