## Why is the atomic mass of aluminum-27?

Aluminum contains thirteen protons and fourteen neutrons in it. So, it’s atomic mass is . i.e. 27 u is the Atomic Mass of Aluminum.

How many protons neutrons or electrons are in aluminum-27?

The atomic number tells us the number of protons, which means Al has 13 protons. Recall that in a neutral element the number of protons and electrons are equal. This means Al has 13 electrons. There are 14 neutrons and 13 electrons in Aluminum-27.

### What element has an atomic mass of 27?

Cobalt
Answer and Explanation: Cobalt, a transition metal, has an atomic number of 27.

### How many atoms are in 27 grams of aluminum?

13 atoms. Hint: Mole is the unit for the number of atoms or molecules of a material. One mole is equal to the Avogadro’s number and each element has a different molar mass depending on the weight. It means 1 mole of aluminium contains \${ 27g }\$ of aluminium.

How do you calculate the atomic mass of Aluminium?

## What is the protons of aluminum-27?

13
Aluminium-27/Protons

## How many protons does aluminum-27 have?

How many protons, neutrons, and electrons are present in an atom of aluminum-27? The number of protons in Aluminium is 13. The 27 means the atomic mass is 27 .

How many electrons does aluminum 27 have?

13 electrons
We know that atoms have neutral electric charge because they have an equal number of positively charged protons and negatively charged electrons. Therefore, the aluminum-27 isotope must have 13 electrons.

### What is the atomic weight of Al27?
