Answer: A
Explanation: Beta particles have a charge of -1
Yes, an electron cause an electromagnetic wave to vibrate.
<h3>What is an electromagnetic wave?</h3>
One of the waves is propagated by simultaneous periodic variations of electric and magnetic field intensity and that includes radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Electromagnetic waves are produced when something vibrates—an electric charge that moves back and forth.
When an electric charge vibrates, the electric field around it changes. Because the electric charge is in motion, it also has a magnetic field around it.
This magnetic field also changes as the charge vibrates.
Therefore, an electron causes an electromagnetic wave to vibrate.

Answer: placing coefficients
Explanation: In a balanced chemical equation, the total number of atoms of each element present is the same on both sides of the equation. Stoichiometric coefficients are the coefficients required to balance a chemical equation. These are important because they relate the amounts of reactants used and products formed.
The number that represents a neutral pH is 7.
Answer:
I think the answer might be because Atomic mass is the weighted average of the naturally occuring isotopes. Also with the fact that it's not an integer, it would almost never be a whole number
