4Protons have a charge of 1+.

Answer 1

Protons have the same magnitude of charge as electrons but are opposite in sign. Most atoms have more protons than electrons. and Protons have a charge of 1+.

Step-by-step explanation:

Statement 1: Protons have the same magnitude of charge as electrons but are opposite in sign. This means that the charge of a proton is positive (+1) while the charge of an electron is negative (-1).

Statement 2: Most atoms have more protons than electrons. In a neutral atom, the number of protons is equal to the number of electrons. However, there can be situations where atoms gain or lose electrons, resulting in an imbalance.

Statement 3: Protons have a mass that is approximately equal to neutrons. Both protons and neutrons have a mass of around 1 atomic mass unit (u). The mass of an electron is much smaller and is negligible compared to the mass of protons and neutrons.

Statement 4: Protons have a charge of 1+. This means they carry a positive charge, while electrons carry a negative charge.
