select 2 correct answer(s)
□ anions
□ elements
□ isotopes
□ cations
question 6 (1 point)
ionic compounds are formed when ions of metallic elements combine with ions of one or more nonmetallic elements by electrostatic forces.
○ true
○ false

Explanation:

First Question (Select all that apply)

• An atom with unequal protons and electrons is an ion. If electrons > protons, it's an anion (negative charge). If protons > electrons, it's a cation (positive charge).
• Elements are neutral (protons = electrons), and isotopes differ in neutrons (protons = electrons in isotopes of the same element). So the correct options are anions and cations.

Ionic compounds are formed between metal ions (cations, lose electrons) and non - metal ions (anions, gain electrons) due to electrostatic attraction (ionic bonds) between opposite charges. So the statement is true.

Answer:

A. anions, D. cations
