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
Answer
Brief Explanations:
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:
- H (Hydrogen)
- 2
