Question

How are these ions distinguished from one another in writing formulas for compounds? A. using Latin prefixes B. using numerical superscripts C. using Arabic numerals D. using Roman numerals

Answer 1

Answer:

B. using numerical superscripts

Explanation:

ion is an atom that has different number of protons and electrons. An isotope is an atom of an element with a specific number of neutrons. Two different isotopes of the same element will have two different neutron counts.

When writing the symbol for an ion, the one- or two-letter element symbol is written first, followed by a superscript. The superscript has the number of charges on the ion followed by a + (for positive ions or cations) or - (for negative ions or anions). Neutral atoms have a charge of zero, so no superscript is given.
