Science test Flashcards
The 3 subatomic particles are called:
Electrons, Neutrons, Protons
The protons and neutrons are found in the
Nucleus
An element that has the same number of protons but a different number of neutrons as the element on the periodic table is known as a
Isotope
The electrons of an atom are found in an area known as
Electron cloud
What tells you the number of protons in a atom
atomic number
The number of protons is equal to the number of what when looking at an atom on the periodic table.
Electrons
To find the number of neutrons in an element, you can subtract the
Atomic mass from the atomic number
The diagram that we used is based on the
bohr model
