Question

10. Name an element represented by the Lewis structure : X: 11 Name an element that is most likely to form an ion with a 3 - charge 12. A chemical bond formed when two atoms share two pairs of electrons is a bond, 13. Which element is most likely to form two covalent bonds? 14. Name an element that has two valence electrons 15. In forming covalent bonds where the octet rule is obeyed, oxygen usually forms bonds and fluorine usually forms bonds (use numbers to fill in blanks) 16. A chemical bond formed when two atoms share two electrons is a bond bonds is said to have a shape, 8. Which element has the highest electronegativity?

I need all please

Answer 1

10) Answer is oxygen. Because given structure contain 6 valence electrons.

11) Answer is nitrogen. Because N needs three electrons to achieve noble gas configuration, hence show -3 charge.

12) Answer is double bond. Double bond is formed by sharing of two pairs of electrons.

13) Oxygen. As it need two electrons to achieve noble gas configuration.

14) Magnesium.

15) oxygen form double bond and fluorine form single bond.

16) Single bond.

17) Tetrahedral.

18) fluorine.
