Question

• if two or more atoms of the same element dont satisfy the octet rule, just enter the chemical symbol as many times as necessary. for example, if two oxygen atoms dont satisfy the octet rule, enter \o,o\.

the symbols of the problem atoms are: *
yes.
no, it has the wrong number of valence electrons.
the correct number is:
no, it has the right number of valence electrons but doesnt satisfy the octet rule.

Explanation:

Step1: Analyze the Lewis - structure of $F_2O$

In $F_2O$, oxygen is the central atom. Fluorine has 7 valence electrons and oxygen has 6 valence electrons.

Step2: Calculate the total number of valence electrons

The total number of valence electrons in $F_2O$ is $2\times7 + 6=20$ valence electrons.

Step3: Check the octet - rule for each atom

Oxygen forms two single bonds with two fluorine atoms. Oxygen has 2 bonding pairs and 2 lone pairs, which gives it 8 electrons around it. Each fluorine atom has 1 bonding pair and 3 lone pairs, which also gives each fluorine atom 8 electrons around it. So, all atoms satisfy the octet - rule.

Answer:

Yes.
