Question

question 3 a molecule consists of two or more atoms with dropdown options: connected, together, unlike, separated by covalent bonds. question 4 partial text: are positively charged ions. options: separated, unlike, together, connected

Explanation:

To complete the sentence "A molecule consists of two or more atoms ____ by covalent bonds", we analyze the options. "Connected" fits as covalent bonds link atoms in a molecule. "Together" is less precise in a scientific context, "unlike" and "separated" don't make sense here as covalent bonds join atoms.

Answer:

connected
