Question

3 multiple choice 1 point the lines in a lewis structure represent: protons in the nucleus non - bonding electrons bonding pairs of electrons shared neutron pairs 4 multiple choice 1 point in a polar bond, the atom with the greater attraction for electrons becomes: slightly negative positively charged neutral a noble gas

Explanation:

Question 3

In Lewis structures, lines represent bonding pairs of electrons (each line is a pair of shared electrons). Protons are in the nucleus (not represented by lines), non - bonding electrons are dots, and neutrons aren't shared in bonds. So the correct option is the one about bonding pairs of electrons.

In a polar bond, the atom with greater electron attraction (higher electronegativity) pulls electrons more, so it gains a partial negative charge (slightly negative). It doesn't become positively charged (loses electrons), neutral (electrons are unevenly distributed), or a noble gas (noble gases are stable with full shells, not related to polar bond electron attraction).

Answer:

C. Bonding pairs of electrons
