What are subscripts and how are they written?

Answer 1

It depends where they are located.

The superscript can be the charge of the compound or Atomic Mass of the atom.

The subscript can be the atomic number of the atom or the number of atoms in a compound.

Superscripts

Mg+2 Magnesium has a +2 charge.

ClO- Perchlorate has a -1 charge.

235U Uranium has an atomic mass of 235 amu.

Subscripts

O2 Each molecule of oxygen has 2 oxygen atoms.

H2SO4 Each sulfuric acid molecule has 2 hydrogens, 1 sulfur, and 4 oxygen atoms.

56Ba Barium has an atomic number of 56. It has 56 protons and 56 electrons.

Answer 3

This is an attempt to describe the rules I've used and heard used. Your mileage may vary. Superscripts indicating multiplicative power (like 109) are usually said "to the" ("ten to the ninth"). 2, 3, and -1 are special cases, often pronounced "square" or "squared", "cubic" "cube" or "cubed", and "per" respectively (-2 is sometimes said as a double "per"): * m3 : cubic meters * c2 : c squared * g mol-1 : grams per mole * m s-2 : meters per second per second If you do say "per" it's assumed to apply to everything after that: * g mol-1 K-1 : grams per mole Kelvin Subscripts in chemistry are usually just said as numbers: * H2O : H two O * H2SO4 : H two S O four If you feel a need to be precise or to indicate that the subscript applies to more than the most recently given element you might actually say "subscript" or "quantity subscript" (it's usually assumed that the person you're talking to knows enough chemistry to figure out what the quantity applies to). * Ca3(PO4)2 : C a three P O four (quantity) subscript two Superscripts for nuclides are said as numbers but moved to the end: * 238U : U (or uranium) two thirty eight
