Question

when electrons transfer from one atom to another, both atoms become choose and they are held together by a(n) choose bond. when electrons are shared between atoms, a(n) choose bond forms between the atoms, and the joined atoms become a(n) choose.

Explanation:

1. When electrons transfer from one atom to another, the atoms become ions (since electron transfer leads to charge imbalance, forming cations and anions), and they are held together by an ionic bond.
2. When electrons are shared between atoms, a covalent bond forms between the atoms, and the joined atoms become a molecule (as covalent bonding typically forms molecules by sharing electron pairs).

Answer:

First "Choose" (for the type of species after electron transfer): ions
Second "Choose" (for the bond type with electron transfer): ionic
Third "Choose" (for the bond type with electron sharing): covalent
Fourth "Choose" (for the species after covalent bonding): molecule
