Protons, Neutrons, Electrons, Isotopes, Ions, and Patterns on the Periodic Table
If Carbon (which has an atomic number of 6) has an isotope with a mass of 13, what would it's notation be?
carbon's notation would be... 13 C OR C-13 6
What are cations?
cations are metals and they are positively charged
What are electrons closest to the nucleus called?
core electrons
What is the atomic mass on the Periodic Table?
the atomic mass on the Periodic Table is an average
What number represents the number of protons?
the atomic number
How can an atom have no charge?
the charges of the protons and electrons balance out to give it no charge
What is an ion?
a charged particle
How is a neutron charged?
a neutron has no charge
What happens to an anion's electrons?
an anion gains electrons
How can an atom have a charge?
an atom has a charge when the number of protons and neutrons are unequal
How is an ionic bond created?
an ionic bond is created when electrons transfer from one atom to another
What are anions?
anions are non-metals and they are negatively charged
What are the chemical properties of elements?
are they losing or gaining electrons
What are the 5 patterns on the Periodic Table?
1. Metals 2. Metalloids 3. Non-metals 4. Periods 5. Groups
What happens to a cation's electrons?
a cation loses electrons
Where in an atom are electrons found?
electrons are found on electron shells (orbitals)
How are electrons charged?
electrons are negatively charged
What are the physical properties of elements?
luster solidity malleability color conductivity ductility brittleness
What subatomic particle creates an isotope?
neutrons can change the mass of an atom, creating an isotope
What is a neutron's relation to a proton?
neutrons hold protons together
How is a proton charged?
positively charged
What two subatomic particles make up the atomic mass?
protons and neutrons make up the atomic mass of an atom
What do the groups on the Periodic Table represent?
the groups represent the number of valence electrons, which identify it as an ion or not
Where in an atom are neutrons found?
the nucleus
Where in an atom are protons found?
the nucleus
What do the periods on the Periodic Table represent?
the periods (1-7) represent the number of valence shell levels (energy levels)
What is an isotope?
the same element with differing mass numbers
What are electrons farthest from the nucleus called?
valence electrons
What happens to an electron that makes an atom negative?
when an atom gains an electron it becomes negative
What happens to an electron that makes an atom positive?
when an atom loses an electron it becomes positive
Do neutrons have a significant mass?
yes, 1 atomic mass unit (amu)
Do protons have a significant mass?
yes, 1 atomic mass unit (amu)
