Magnesium chloride is a salt formed with ionic bonds between one magnesium ion and two chloride ions. Magnesium has two electrons in its outer shell and chlorine has seven electrons in its outer shell. How are the electrons transferred between these atoms?

Answers

Magnesiumchloride is formed when a magnesium atom donates one electron each to two chlorine atomsto form magnesium ions and chloride ions.

What are ionic compounds?

Ionic compounds are compounds which are formed between oppositely charged ions.

The negatively-charged ions are formed by electron gain from the positively-charged ions.

In the magnesium chloride salt, a magnesium atom donates one electron each to two chlorine atoms.

The ions are held together by strong electrostatic forces of attraction to form the ionic compound.

Answer:

The magnesium atom loses 2 electron to the 2 atoms of chlorine. The 7 valency electrons of each chlorine atom will now be 8 to attain stable configuration. The final compound is written as MgCl2.

Explanation:

Ionic compounds are compound formed from the transfer of electron(s). One atom of the element loses electron(s) while the other atom gains electron(s).

The compound Magnesium chloride is an ionic compound . The bond between an atom of magnesium and 2 atoms of chlorine is an ionic bonding.

The valency electron of magnesium is 2 electron , for the atom of magnesium to attain octet rule, it will easily lose it 2 electrons to the chlorine atoms.

The chlorine atom on the other hand has 7 valency electrons, to attain octet configuration it will most likely gain 1 electron to become stable.

The magnesium atom loses 2 electron to the 2 atoms of chlorine. The 7 valency electrons of each chlorine atom will now be 8 to attain stable configuration. The final compound is written as MgCl2.

Which formula represents a molecular compound?
(1) Kr (3) N2O4
(2) LiOH (4) NaI

Answers

N2O4 is the only option from the list that represents a molecular compound, since compounds must contain at least two different atoms, although these can be from different groups.

Answer: Option (3) is the correct answer.

Explanation:

A molecular compound is a compound in which atoms used to share electrons and thus results in the formation of covalent bonds.

For example, $N_(2)O_(4)$ is a covalent compound and hence, it is a molecular compound.

Whereas LiOH and NaI are ionic compounds as their atoms has transferred electrons.

Therefore, we can conclude that out of the given options, $N_(2)O_(4)$ is the formula which represents a molecular compound.
