### Where can protons and neutrons be found?

the nucleus
Protons and neutrons are heavier than electrons and reside in the nucleus at the center of the atom. Electrons are extremely lightweight and exist in a cloud orbiting the nucleus.

What has 20 neutrons and protons?

calcium
As you know, the nucleus of an atom contains protons, which are positively charged particles, and neutrons, which are neutral particles. An atom’s mass number will always tell you how many protons and neutrons its nucleus contains. In your case, you know that an atom of calcium, Ca , has 20 neutrons in its nucleus.

What element has 18 protons and 22 neutrons?

Argon
Given the number of protons is \[18\]. So, the atomic number is also \[18\], and the element with atomic number \[18\] is Argon with the symbol \[Ar\]. Now we need to find the mass number of Argon. Since, a neutral atom of argon also has 22 Neutrons.

## What element has 2 protons neutrons?

Helium
Helium is the second element of the periodic table and thus is an atom with two protons in the nucleus. Most Helium atoms have two neutrons in addition to the protons. In its neutral state, Helium has two electrons in orbit about the nucleus. Model of a helium atom’s nucleus with two protons and two neutrons.

### What element has most neutrons?

The atom with the largest number of neutrons is a tie between livermorium and tennessine. Each of these atoms contain 177 neutrons.

What is the proton symbol?

Proton

The quark content of a proton. The color assignment of individual quarks is arbitrary, but all three colors must be present. Forces between quarks are mediated by gluons.
Classification Baryon
Interactions Gravity, electromagnetic, weak, strong
Symbol p , p + , N + , 1 1H +
Antiparticle Antiproton

Are all protons the same size?

Was hoping one of you all knew the answer. All protons are exactly the same. This includes their size. Electrons probably don’t have a size, but if they do, they all have the same size.

## Can you have 0 neutrons?

There is only one stable atom that does not have neutrons. It is an isotope of the element hydrogen called protium. Protium, which contains a single proton and a single electron, is the simplest atom. All other stable atoms contain some number of neutrons.

### What has 17 protons and 18 neutrons?

Chlorine-35
