Why will a sound wave travel through a solid more quickly than through a gas?
Group of answer choices

The particles in a gas are close together, which means the vibrations of the sound wave transmit more slowly.

The particles in a gas are spaced farther apart, which means the vibrations of the sound wave transmit more quickly.

The particles in a solid are spaced farther apart, which means the vibrations of the sound wave transmit more quickly.

The particles in a solid are closer together, which means the vibrations of the sound wave transmit more quickly.

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.
