Mass number

We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons.

How much protons and neutrons does sodium have?

The element Sodium has an atomic number of 11 and an average atomic mass of 22.98 which makes the mass number 23. An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 – 11 this atom will have 12 neutrons.

How many protons does sodium 24 have?

The atoms of both isotopes contain 11 protons, but sodium-23 has 12 neutrons whereas sodium-24 has 13.

How many neutrons does sodium have?

Given the fact that there are 12 neutrons in sodium, the complete symbol for sodium is 2311Na.

How many neutrons are in CA?

The number of neutrons will be the same as the number of protons: it is also 20.

How many electrons protons and neutrons are there in an atom of sodium if sodium has an atomic number of 11 and a mass of 23?

An atom of sodium has 11 protons, 12 electrons, and 11 neutrons.

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.

How many electrons does NA 1 have?

1 Expert Answer

Sodium’s atomic number is 11. A neutral atom, Na, would have 11 electrons. But this is Na+1. The “+1” tells us that it is missing one electron.

How many neutrons are in hydrogen?

A hydrogen atom contains one proton, one electron, and no neutrons. The nucleus of a helium atom contains two protons and two neutrons, and the helium atom has two electrons.
