If an atom has 17 protons, 14 neutrons, and 19 electrons, what is the atom's electrical charge?

Negative

Explanation:

Protons have a positive electrical charge and electrons have a negative electrical charge. One proton's charge is the same "strength" as one electron's charge so since there are two more electrons, it is a negative charge.

Say there were two protons and one electron. It would be a positive charge. Now I ask, if there are 43 electrons and 43 protons, would it be positive or negative? Trick question! Neither, because they cancel each other out.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
