- 1what are the properties of an ElectronHas a negative charge of -1
has a mass of 0 or 1/1836
is located outside the nucleus - 2what are the properties of a NeutronHas a neutral charge of 0
is located outside the nucleus - 3what are the properties of a ProtonHas a positive charge of 1
Has a mass of 1
Located inside the nucleus - 4what is an IonAtom with a net charge (not neutral). This happens when there is an unequal amount of protons and electrons.
- 5what is an IsotopeAtoms of an element with the same number of protons and a different number of neutrons
- 6Example of an Isotope
- 7what are the steps to find the average atomic mass1. Make the percentage into a decimal by moving the decimal 2 places to the left.
2. Multiply each percentage (in decimal form) why its corresponding mass number
3. Add the resulting products for each isotope
4. Write answer in AMU - 8How to determine the number of: ProtonsThe number of protons are the same as the element's atomic number
- 9How to determine the number of: Protons if there is a negative chargeAdd the charge to the number of protons
- 10How to determine the number of: Neutrons If there is a neutral chargeMass number - atomic number = neutrons
- 11How to determine the number of: Protons if there is a positive chargeSubtract the charge from the number of protons
- 12How to determine the number of: Electrons if there is a neutral chargeThe number of electrons are the same as the number of protons
- 13How to determine the number of: Electrons if there is a positive chargeSubtract the charge from the number of protons
- 14How to determine the number of: Electrons if there is a negative chargeAdd the charge to the number of protons
- 15What do you do if the atomic mass is not given?Use the atomic mass from the periodic table and round it to the nearest whole number
- 16anionnegatively charged Ion
- 17cationpositively charged ion
(paw-sitively charged) - 18Where is most of the atom's mass locatedThe Nucleus
- 19What is the charge of a protonpositive
- 20What is the charge of a neutronneutral
- 21what is the charge of an electronnegitive
- 22What is the term for protons and neutrons together?nucleons
- 23Which subatomic particle is unique for each element?protons
- 24what type of atoms differ in their number of neutronsisotopes
- 25What does the atomic number tell you?how many protons are within its atom
- 26what is the average mass of the different isotopes of an elementatomic mass
- 27what does 14 mean in Carbon-14the mass number
- 28what is the charge of the nucleus and whypositive
protons - positive
neutrons - negitive
