Question

What is the atomic mass of Magnesium?

Answer 1

Hint: We have to remember that the magnesium it is a metal since it has all metallic properties like it is a good conductor of heat and electricity also it is a lustrous metal. It appears to be shiny grayish in appearance. Magnesium is very similar to beryllium as both are placed in the same group.

Complete answer:
We have to know that magnesium is a chemical element that is present in a periodic table having atomic number $$12$$. Atomic symbol for magnesium is $$Mg$$. It belongs to group $$2$$ i.e. alkaline earth metals. Since magnesium has all metallic properties like it is a good conductor of heat and electricity also it is a lustrous metal. It appears to be shiny grayish in appearance. Magnesium is very similar to beryllium as both are placed in the same group.
Since metals usually have a low melting point. Magnesium being a metal has a low melting point. The most common oxidation state of magnesium is $+2$ and $+1$ i.e. a strongly basic oxide
Electronic configuration of Magnesium: $$\left[Ne\right]3s^2$$
Magnesium has filled electronic configuration.
Mass number of magnesium is $$24$$ amu which is approximately double the atomic number i.e. $$12$$. The number of protons is the same as that of atomic number which is $$12$$, and number of neutrons can be found by differentiating between mass number and number of protons i.e. $$12$$.

Note:
We need to remember that the protons carry positive charge, electrons carry negative charge whereas a neutron is a neutral species that has zero or no charge. Number of neutrons is different in isotopes. Magnesium belongs to s block elements, it is an alkali metal which belongs to group $$2$$.
