Question

what is the lewis diagram for fluorine, f₂? (note: just fill in the dashes, not the dots.) 5. think and discuss: how is the formation of covalent bonds similar to kids sharing markers? how is it different? if possible, discuss your answer with your classmates and teacher. activity b: building molecules get the gizmo ready: click reset. turn off show lewis diagram. select oxygen. question: how do atoms share more than one pair of electrons? 1. observe: like fluorine and most other elements, oxygen atoms are most stable with a full complement of eight valence electrons. a. how many valence electrons does each oxygen atom have now?

Explanation:

Step1: Recall oxygen's electron - configuration

Oxygen has atomic number 8. Its electron - configuration is 1s²2s²2p⁴.

Step2: Determine valence electrons

Valence electrons are in the outermost shell. For oxygen, the outermost shell is the second shell (n = 2), and it has 2 + 4=6 valence electrons.

Answer:

6
