If you remove one neutron from helium, the remainder is what element?

1 answer:

4 0

If you remove one neutron from helium, the remainder element remains the same but it become the isotope of helium. Because if the number of neutrons are changes in the element, they are the isotopes of the that element. And if you remove the one proton from helium then it will become another element that is hydrogen.

The density of Mg is 1.74g/cm3. The density of strontium is 2.60g/cm3. What would you expect the density of Ca to be?

Tomtit [17]

The density of Ca will be between that of Mg and Sr

Explanation:

Ca, Mg and Sr are group II elements. They are called alkali earth metals. The correct order of the elements in this group are: Be, Mg, Ca, Sr, Ba and Ra.

Density is an intensive property of matter which describes the amount of matter(mass) per volume of a substance.

Density varies proportionally with mass. The higher the mass, the higher its density.
On the periodic table, atomic mass which the number of protons and neutrons in the nucleus of an atom increases down the group.
This implies a progradation in the value of density down the group. Therefore one expects that the value of density of Ca will fall between that of Mg and Sr. It cannot be more than 2.6g/cm³ nor less than 1.74g/cm³.
