The 2 regions or areas of an atom
What are the nucleus and the electron cloud?
The two kinds of subatomic particles have about the same amount of mass
What are protons and neutrons?
Particles that stretch out from the nucleus adding greater volume to an atom.
What are electrons in/on the energy levels/electron cloud?
This number sentence will help you figure out the # of neutrons an atom has
What is the ATOMIC MASS--PROTONS?
The smallest part of an element that can still be considered matter.
What is an atom?
The 3 subatomic particles that make up an atom
What are protons, neutrons, and electrons?
The charge of a proton
What is (+) positive?
This part of the periodic card tells you the # of protons in an atom
What is the atomic number?
These subatomic particles are found in/on the energy levels/electron clouds
What are electrons?
Particles smaller than an atom that are not matter.
What are subatomic particles?
Subatomic particle that determines the identity of an atom (the FINGERPRINT)
What are protons?
The charge of a neutron
What is (no charge) neutral?
The number of electrons that can fit on first orbit
What is 2?
In a stable atom, the number of electrons are always equal to the number of these.
What are positive protons ?
The number of electrons that can fit on the 2nd orbit. It is the same amount that can fit on the 3rd orbit for the atoms we are drawing.
What is 8?
Particle(s) found is the nucleus
What are protons and neutrons?
The charge of an electron
What is (-)negative?
The area of an atom where most of the mass is found
What is the nucleus?
The number of this type of subatomic particle never changes
What are protons?
The reason you can never trust atoms.
What is "they make up everything"?
The number of elements are on the periodic table
What is 118?
The atomic model, created in 1913, that depicts electrons orbiting around a central nucleus.
What is a Bohr model?
The row of the periodic table an element is in tells you how many of these an atom has.
What are orbitals/clouds/layers/shells?
The word for alternate versions of the same kind of atom that contains an extra neutron or 2
What are isotopes?
An organized chart that gives you information about the atoms of all the elements and shows ways that they are alike and different.
