In an ionic bond, electrons are ___________________. Choose all the apply.
(12pts + Brainlest)
1. gained
2. lost
3. shared
4. neutral
Answers
Answer:
Electrons are shared.
Explanation:
In an ionic bond, electrons are gained and lost. So, the correct options are A and B.
What is an ionic bond?An atom can establish bonds with other atoms in two main ways: covalent and ionic. The sharing of electrons between two or more atoms forms a covalent connection. When two or more ions join contact, they can create ionic bonds that are held together by charge differences.
A chemical link in which one atom transfers one or more electrons to another atom is known as an ionic bond. A negatively charged ion, or anion, is created when an atom receives electrons, while a positively charged ion, or cation, is created when an atom loses electrons. The ions' opposing charges draw to one another and create a solid link between them. Usually, a metal and a non-metal atom form ionic connections. Ionic bonds contain electrons.
So, the correct options are A and B.
