Question

1. Atoms with filled outermost energy levels tend______ to participate in chemical reactions. (not)

2. In an ionic bond, _______ atoms of opposite charge are held together by __________ attraction. (charged), (intermolecular)

3. Most atoms tend to undergo _______,combining ways that cause their atoms to become more_____. (chemical reactions), (stable)

4. A bond formed by electriacal attraction between two opposite charged ions is called. (ionic bonding)

5. A chemical reaction that can proceed forward or backward is a _____ (redox reaction)

Can you please tell me if the answers in the parehtneses are correct or not? If not, can you tell me the correct answer?

Answer 1

1 and 5 are definitely wrong.

Answer 2

1 no because the outer orbitals contain the valence electrons (total electrons - atomic number).

2 yes because electrons shared is a intermolecular interaction

3 yes this is energetically favorable (and this is chemistry)

4 yes

5 no because this is an equilibrium reaction. Strong electrolytes are reactants that go completely to products (very close). Weak electrolytes are products that do not completely go to products, but the products reform to a degree to form products again. Thus you have an equillibrium of products and reactants in the system.
