Question

which of the following elements would make one covalent bond? o (oxygen) none are correct c (carbon) ne (neon) h (hydrogen) question 2 (1 point) how many covalent bonds would be made between two o (oxygen) atoms? 3 1 4 2 none are correct

Explanation:

For the first question, hydrogen has one valence electron and needs one more to achieve a stable - electron configuration, so it forms one covalent bond. Oxygen has 6 valence electrons and forms 2 covalent bonds to complete its octet, carbon has 4 valence electrons and forms 4 covalent bonds, and neon is a noble gas with a full - valence shell and is chemically inert.
For the second question, each oxygen atom has 6 valence electrons. To complete their octets, two oxygen atoms share 2 pairs of electrons, forming a double covalent bond (2 covalent bonds).

Answer:

1. H (Hydrogen)
2. 2
