An atom is determined to contain 17 protons, 18 electrons, and 18 neutrons. what are the mass number and charge of this atom or ion?
mass number: 36, charge: -1
mass number: 35, charge: +1
mass number: 35, charge: -1
mass number: 36, charge: neutral

Particle model to predict what will happen if a sharp object creates a hole in the soccer ball

Given the following information: mass of proton = 1.00728 amu mass of neutron = 1.00866 amu mass of electron = 5.486 × 10^-4 amu speed of light = 2.9979 × 10^8 m/s calculate the nuclear binding energy (absolute value) of 3li^6. which has an atomic mass of 6.015126 amu. j/mol.

If 3 moles of a compound use 24 j of energy in a reaction, what is the a hreaction in j/mol?
