An atom has 32 protons, 40 neutrons, and 32 electrons. What is the charge of the atom’s nucleus?
eimsori [14]
The charge is neutral.

To find the charge, subtract the number of electrons from the number of protons. Because they are the same, there is no charge.

The balanced nuclear equation for the β emission of the following isotopes is seen below:

92                 92                0

Sr            ⇒ Y         +   e

38                  39             -1

<h3>What is Beta emission?</h3>

This is also known as beta decay in which a beta ray is emitted from an atomic nucleus.

In a neutral atom, the number of protons is always equal to what other part of the atom?
Licemer1 [7]

Answer:

b. The number of electrons

Explanation:

A "neutral atom" has a <u>neutral charge</u>. This means that <em>its charge is equal to </em><em>zero. </em>In order for the charges to cancel out each other, the atom's <em>positive charge should be equal to the negative charge. </em>These being said, the number of electrons<em> (negatively-charged)</em> is then equal to the number of protons <em>(positively-charged). </em>Those atoms which are not neutral are called <em>"ions."</em> This means that they either have more or less electrons than the protons.

Which actions represent endothermic reactions? Check all that apply. an instant ice pack becoming cold, splitting a gas molecule
DerKrebs [107]
Answer is: an instant ice pack becoming cold, splitting a gas molecule and baking bread.

<span>Endothermic reaction is chemical reaction that absorbs more energy than it releases.
</span>In ice pack, <span>reaction absorbs heat from the surroundings (endothermic reaction), lowering the surrounding temperature.
For splitting molecule and baking bread we must add energy to break bonds between atoms.</span>
