Magnesium fluoride contains only magnesium and fluorine. what is the formula for this compound? express your answer as a chemical formula

Explanation:

Atomic number of magnesium is 12 and its electronic configuration is 2, 8, 2. So, to acquire stability it loses 2 valence electrons and hence forms ion.

Whereas atomic number of fluorine is 9 and its electronic distribution is 2, 7. And, to attain stability its needs to gain one electron and hence then it forms ion.

Therefore, when both magnesium and fluorine chemically combine together then magnesium atom will donate its 2 valence electrons to the fluorine atom.

Hence, they will tend to form magnesium fluoride, that is, .

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
