5.1 Atomic Structure Flashcards
Proton Charge
Positive
Proton Mass
1 amu
Proton Location
The nucleus
Proton Role in Atom
Determine the identity of an atom
Neutron Charge
Neutral / None
Neutron Mass
1 amu
Neutron Location
Nucleus
Neutron Role in Atom
Holds the nucleus together
Electron Charge
Negative
Electron Mass
Relatively 0 amu
Electron Location
Moves around the nucleus
Electrons Role in Atom
Gives the atom a fuzzy edge
Isotope Definition
Atoms of the same element with different masses due to differences in neutrons.
Does + and - attract or repel
Attract
Does + and + attract or repel
Repel
Does - and - attract or repel
Repel
The relationship between coulombic attraction and amount of charge
The amount of charge and the attraction have a direct relation.
The relationship between coulombic attraction and distance
The distance and the attraction have an inverse relation
Definition of electronegativity
Determine the atomic mass, element, and ion charge
16 protons
16 neutrons
18 electrons
Atomic mass - 32
Element - sodium
ion charge - -2
An atom of Calcium has an atomic mass of 41 and a net charge of +2
Determine the # of protons, electrons, and neutrons
Protons - 20
Neutrons - 21
Electrons - 18
Explain why isotopes can be useful in scientific research
Isotopes can give off radioactivity in places like the body helping the be able to pin point and they will have a different mass causing a difference in data.
