Question

4, which particle(s) affect the atomic mass of your atom? what effect does each of the three particles have on the mass of an atom? 5, develop a relationship (in the form of a single sentence or equation) that can predict the mass of an atom. 6, which particle(s) affects the charge of an atom? what effect does each of the three particles have on the charge of an atom?

Explanation:

Step1: Identify mass - affecting particles

Protons and neutrons have significant mass and affect atomic mass. Electrons have negligible mass compared to them and do not contribute significantly to atomic mass.

Step2: Analyze the effect of each particle on mass

Protons have a mass of approximately 1 atomic mass unit (amu). Neutrons also have a mass of about 1 amu. The sum of the number of protons and neutrons in the nucleus gives the mass - number of the atom which is a close approximation of the atomic mass.

Step3: Develop mass - prediction relationship

Atomic mass (approximate) = Number of protons + Number of neutrons.

Step4: Identify charge - affecting particles

Protons and electrons affect the charge of an atom. Protons are positively charged (+1 elementary charge), electrons are negatively charged (- 1 elementary charge), and neutrons are neutral.

Step5: Analyze the effect of each particle on charge

If the number of protons equals the number of electrons, the atom is neutral. If there are more protons than electrons, the atom is a positively - charged ion (cation). If there are more electrons than protons, the atom is a negatively - charged ion (anion).

Answer:

1. Protons and neutrons affect the atomic mass of an atom. Protons have a mass of approximately 1 amu and neutrons have a mass of about 1 amu, contributing to the overall mass of the atom. Electrons have negligible mass and do not significantly affect atomic mass.
2. Atomic mass (approximate) = Number of protons + Number of neutrons.
3. Protons and electrons affect the charge of an atom. Protons carry a positive charge (+1 elementary charge), electrons carry a negative charge (-1 elementary charge), and neutrons have no charge. If the number of protons = number of electrons, the atom is neutral; more protons make it a cation, more electrons make it an anion.
