## What is the proton of magnesium?

12
Magnesium/Atomic number

## What is the electron of magnesium?

Name Magnesium
Number of Protons 12
Number of Neutrons 12
Number of Electrons 12
Melting Point 650.0° C

## How many neutrons are in Boron?

6 neutrons
The mass number for boron is 5; this The atomic mass of boron (symbol B) is 10.8. To determine the number of neutrons we round 10.8 to 11 and subtract the atomic number (5) and get 6; therefore, boron has 6 neutrons.

Mg
Magnesium/Symbol

## How do you get the number of neutrons?

To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.

## What are three properties of magnesium?

Chemical properties of magnesium – Health effects of magnesium – Environmental effects of magnesium

## Which element has the most neutrons?

Uranium, for example, has the largest naturally occurring nucleus with 92 protons and over 140 neutrons. You can figure out the most common configuration of elements by looking at the periodic table of elements.

## What are the number of neutrons in magnesium?

It depends on the isotope of magnesium. There are three stable isotopes, which have 12, 13 and 14 neutrons respectively. However, isotopes of magnesium can extend all the way from 7 neutrons to 28 neutrons, albeit some of these isotopes are VERY unstable.

## What element has 10 neutrons?

Each neon atom has 10 protons. There are three stable isotopes of the element, with atoms having 10 neutrons (neon-20), 11 neutrons (neon-21), and 12 neutrons (neon-22).

## What are the number of neutrons in each element?

These different versions are called isotopes and most elements are actually a mixture of different isotopes. If you could grab atoms of krypton and count the number of neutrons each one had, you would find that most would have 48 , others would have 47 , some would have 50 , some others would have 46 , a few would have 44 and a very few would have 42 .
