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)
