What number is bigger mass number or atomic
Mass
What does the atomic number show
Number of protons
What does the mass number show
Number of protons and nutrons
What charge do neutral atoms have
None - 0
Number of protons = number of electons true or false
True
What was jj thompson theory on atoms
Plum pudding contained pos charged puddling with neg charges particles electrons
Rurthewoods theory
Gold foil showed most atom is emty space pos charge nucleus in the middle
Bohr model
Electons exist in shells orbiting posit nucleus
What is an isotope
Same element different form as they have different number of neurons but Same number of protons
What does the period show about electronic structure
Number of shells
What is ionic bonding
When atoms loose or gain electrons to form charged particles
