# What does a neutral atom of aluminum-27 contains?

## What does a neutral atom of aluminum-27 contains?

Since you’re dealing with a neutral atom, the number of electrons that surround the nucleus must be equal to the number of protons found in the nucleus. Therefore, the aluminium-27 isotope will have 13 electrons surrounding its nucleus.

What is the a of Al 27?

Aluminium-27 atom is the stable isotope of aluminium with relative atomic mass 26.98153 and nuclear spin (5)/2. A metallic element that has the atomic number 13, atomic symbol Al, and atomic weight 26.98.

How many electrons does an atom of aluminum-27 have?

13 electrons
Aluminum-27 is the only stable isotope of this metal, and it has 14 neutrons, 13 protons and has 13 electrons in the neutral atom.

### How many neutrons are in an atom of aluminum-27?

14
The number of protons in Aluminium is 13. The 27 means the atomic mass is 27 . The number of protons plus the number of neutrons is 27. That means the number of neutrons is 27–13=14.

What is the atomic number of an atom has 27 protons?

The cobalt atom has 27 protons as seen in the periodic table. There are also 27 electrons because the charge is 0. There are 33 neutrons because 60-27 = 33.

How many electrons does the element aluminum contain if its mass number is 27 and the number of neutrons is 14?

Therefore, for an atom of aluminum, there are 13 electrons inside it. So we’ve demonstrated that for an aluminum atom which has the atomic number of 13 and has a mass number of 27, there are 13 protons, 14 neutrons, and 13 electrons.

#### What is the protons of aluminum 27?

13Aluminium-27 / Protons

What is the number of protons in the nucleus of aluminium-27?

This means that any atom that is an isotope of aluminium will have #13# protons in its nucleus. Since you’re dealing with a neutral atom, the number of electrons that surround the nucleus must be equal to the number of protons found in the nucleus. Therefore, the aluminium-27 isotope will have #13# electrons surrounding its nucleus.

### What is aluminium-27 isotope?
