Explanation:
This should be of help:
An atom is made up of three subatomic particles:
- Protons are the positively charged particles.
- Electrons are the negatively charged particles.
- Neutrons do not carry any charges.
A neutral atom is an atom that has not lost or gained any amount of electrons.
In a neutral atom;
the number of protons and electrons are the same
Usually atoms are designated this way:
ᵃₙX
where X is the symbol of the atom
a is the mass number of the atom
n is the atomic number of the atom
The mass number = number of protons + number of neutrons
Atomic number = number of protons
Note; atomic number is the same as the number protons and the number of electrons in a neutral atom.

Hello.
<span>Any number of disturbances, including loud noise or a skier's motion, can cause an avalanche. Even pollution in the Northeast can find its way to Europe, hitching a ride with prevailing winds and causing avalanches in the Alps. That's because snowpack conditions affect the likelihood of avalanches. Soot warms snow and ice faster, creating melt and weakening snow layers, which promulgates avalanches.

Have a nice day
