(SeeFundamental Particles of Matterfor more information.) The mass of the electron is 9.109*10−31kg. Its relative mass is 5.489*10−4amu Electrons have a negative (−1) electric charge. In a stable atom (not an ion) the number of electrons equals the number of protons in the ...

This exceedingly simple and generic mass equation retrodicts the masses of a representative set of 27 well-known particles with an average relative error of 1.6%. A more rigorous mass formula, which includes the total spin angular momentum rule of Quantum Mechanics, the canonical spin values of ...
Counting Subatomic Particles Z = Atomic number (from Periodic Table) # of p+ = # of e- in a neutral atom A = Atomic Mass Number (from the nucleus) it is not the Average Atomic Mass # of p+ + # of n0 Charge = the number of electrons lost or gained. Isotopes: Same element but ...

Subatomic Particles That Make Up Atoms There are 3 types of subatomic particles. 1. electrons (e–) : outside nucleus “-” charge very little mass 2. protons (p+) : make up nucleus “+” charge 1 amu (atomic mass unit) 3. neutrons (n0): make up nucleus no charge 1 amu ...
Which of the following subatomic particles has the smallest mass? a. a neutron b. an electron c. a proton Structure of Atoms: Atoms are made of a nucleus that contains protons and neutrons. Protons are positively charged and neutrons have no charge. Outside ...
Question: A positively charged subatomic particle found in the nucleus is called a(n): A. proton B. electron C. neutron D. nucleus E. orbital Subatomic Particle: Subatomic particles are those particles that can be found out inside the atom. There...
Subatomic particles What information would you get about an element from the periodic table? What is its atomic number and atomic mass? A bohr model of an atom. Notice the protons and neutrons in the nucleus and the electrons outside the nucleus Which element is this? What is its atomic nu...
Instead, the up and down quarks are imbued with a special ability not known to the other particles in the realm. They can feel thestrong nuclear force. That is by far the most powerful force, gluing together the quarks so intensely that a single one can never be seen in isolation. That...
