Question

use your knowledge of valence electrons and bond formation to complete the following description. (2 points)
one carbon atom (group 14) bonds with 4 atoms (group 1) to form the
methane (ch₄). the carbon atom shares with each hydrogen atom, forming

Explanation:

1. Group 1 elements in the context of methane (CH₄) are Hydrogen (H). So the first blank (atoms from Group 1) should be Hydrogen.
2. The compound formed is methane (CH₄), so the second blank is the compound name, which is methane (already given in the problem's context, but the dropdown is for the compound, so it's methane).
3. Carbon has 4 valence electrons and needs 4 more to complete its octet. Each hydrogen has 1 valence electron and needs 1 more. So carbon shares 1 pair of electrons (a single bond, which involves sharing one pair of electrons) with each hydrogen.
4. The type of bond formed between carbon and hydrogen in methane is a single covalent bond (since they share a pair of electrons).

Answer:

First dropdown: Hydrogen
Second dropdown: Methane
Third dropdown: one pair of electrons
Fourth dropdown: a single covalent bond
