# How many valence electrons does sodium 23 have?

## How many valence electrons does sodium 23 have?

one valence electron
Sodium has one valence electron. Valence electrons are electrons found in the outermost shell of an atom.

### How many valence electrons does sodium have?

A: An atom of a group 1 element such as sodium has just one valence electron. It is “eager” to give up this electron in order to have a full outer energy level, because this will give it the most stable arrangement of electrons. You can see how this happens in the Figure below.

#### How many neutrons are in an atom of sodium 23?

12 neutrons
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.

Does sodium have 1 valence electrons?

A: An atom of a group 1 element such as sodium has just one valence electron. It is “eager” to give up this electron in order to have a full outer energy level, because this will give it the most stable arrangement of electrons.

What is the valence of the sodium ion?

Sodium has one valence electron.

## How many protons neutrons and electrons are in sodium-23?

So sodium has 11 protons and 11 electrons. The mass number is 23. The number of neutrons = mass number – atomic number. The number of neutrons = 23 – 11 = 12.

#### How many protons electrons and neutrons does sodium-23 have?

What is the symbol of sodium-23?

Sodium-23 atom is the stable isotope of sodium with relative atomic mass 22.989770, 100 atom percent natural abundance and nuclear spin 3/2. A member of the alkali group of metals. It has the atomic symbol Na, atomic number 11, and atomic weight 23.

How many electrons does sodium 23 have?

Also know, how many electrons does sodium 23? 11 electrons . Subsequently, question is, why is the atomic mass of sodium 23? Sodiumis the element, thus, it has 11 protons.

## What is the valence electron of sodium?

The valence electron is the total number of electrons in the last orbit (shell). The total number of electrons in the last shell after the electron configuration of sodium is called the valence electrons of sodium (Na). The valence electrons determine the properties of the element and participate in the formation of bonds.

### What is the atomic number of sodium (Na)?

The atomic number of sodium (Na) is 11. The atomic number is the number of protons. That is, the number of protons in the sodium (Na) is 11. Electrons equal to protons are located in a circular shell (orbit) outside the nucleus.

#### What is the number of protons and neutrons in sodium?

Protons and neutrons are located in the nucleus. The atomic number of sodium (Na) is 11. The atomic number is the number of protons. That is, the number of protons in the sodium (Na) is 11. Electrons equal to protons are located in a circular shell (orbit) outside the nucleus.
