## What has 18 protons and 22 neutrons?

Argon 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. So, it is clear that this is not an isotope but a neutral atom of Argon.

## What atom has 16 neutrons?

if you look at the periodic table, phosphorus has 15 electrons and protons, and 16 neutrons.

## How do you find the number of neutrons?

For all atoms with no charge, the number of electrons is equal to the number of protons. The mass number, 40, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.

## What has 32 protons and 38 neutrons?

Germanium-70 is composed of 32 protons, 38 neutrons, and 32 electrons.

## What element has 18 protons and 22 neutrons?

Argon 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. So, it is clear that this is not an isotope but a neutral atom of Argon.

## How do u find neutrons?

For all atoms with no charge, the number of electrons is equal to the number of protons. The mass number, 40, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.

## What has 16 protons and 18 neutrons?

So, if there are 16 protons, the element must be sulfur. The mass number for this isotope is 34 – there are 16 protons and 18 neutrons.

## What element has 22 neutrons?

argon Since, a neutral atom of argon also has 22 Neutrons.

## Which element has 15 neutrons?

Therefore the isotope with 14 protons and 15 neutrons is Silicon-29.

## How many neutrons are in each element?

For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28. The most common isotope of uranium has 92 protons and 146 neutrons. Its atomic number is 92 and its atomic mass is 238 (92 + 146)….2.1 Electrons, Protons, Neutrons, and Atoms.

## How do you find neutrons and electrons?

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

## What has 33 protons and 42 neutrons?

Arsenic Arsenic as 33 protons and 42 neutrons in its nucleus giving it an Atomic Number of 33 and an atomic mass of 75. Arsenic is in Period 4 of the Periodic Table because it has 4 electron shells.

## What element has 4 protons and 5 neutrons?

beryllium 4 protons, 5 neutrons, and 4 electrons are there in an atom of beryllium.

## How many protons does calcium have?

20Calcium / Atomic number If we could weigh individual atoms of calcium we would find some variation in their mass; this must be due to variations in the number of neutrons in their nucleus as all must have the same number of protons – 20. Atoms which have the same atomic number but different mass numbers are isotopes.

## What is in a neutron?

A neutron is made of 3 quarks, one up quark, and 2 down quarks and many many "intermediate particles" called gluons which carry the interaction between the quarks. These gluons are exchanged very often, so the quarks feel each of other. Neutrons do not always decay.
