What is the difference between atomic mass and atomic number?
family or group
the number of mass vs the number of electrons in an element
the atomic number is the number of protons and the atomic mass is the protons + neutrons
nothing they're the same
What is an atom?
smallest unit into which matter can be divided without the release of electrically charged particles
what the world is made of
a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign
atoms aren't real
What is a proton?
the central and most important part of an object, movement, or group, forming the basis for its activity and growth
a neutron
a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign

What is a nucleus?
the middle of a cell
the central and most important part of an object, movement, or group, forming the basis for its activity and growth
what a baby starts as
a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy
What is the difference between nuclear fusion and nuclear fission?
What is nuclear fusion?
fusion and stuff with a nuclear force
a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy
a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy

What is nuclear fission?
a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy
a nucleus
an ionic bond
a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy
What are the noble gases?
the different groups on the periodic table
any of the gaseous elements of the periodic table
the chemicals from Chernobyl that made Caleb's head so big
the weird movements Xavier does every time he talks
What is a covalent bond?
type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound
the interatomic linkage that results from the sharing of an electron pair between two atoms
any of the gaseous elements of the periodic table
what happened to make George's forehead ginormous
What is an ionic bond?
two people in a relationship (don't get uncomfortable Mrs. Deroche)
type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound
the interatomic linkage that results from the sharing of an electron pair between two atoms
the type of chemical bond between atoms in a metallic element, formed by the valence electrons moving freely through the metal lattice
What is a metallic bond?
Ms. Dryden
the interatomic linkage that results from the sharing of an electron pair between two atoms
the type of chemical bond between atoms in a metallic element, formed by the valence electrons moving freely through the metal lattice
type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound
What is a Gamma ray?
ionizing radiation consisting of alpha particles, emitted by some substances undergoing radioactive decay
penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei
a fast-moving electron emitted by radioactive decay of substances. (The emission of beta particles was originally regarded as a ray
What is an alpha ray?
a fast-moving electron emitted by radioactive decay of substances. (The emission of beta particles was originally regarded as a ray
ionizing radiation consisting of alpha particles, emitted by some substances undergoing radioactive decay

A gamma ray is deadly
true
false
What is a beta particle?
a fast-moving electron emitted by radioactive decay of substances. (The emission of beta particles was originally regarded as a ray
penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei
ionizing radiation consisting of alpha particles, emitted by some substances undergoing radioactive decay
What is half-life?
the time taken for the radioactivity of a specified isotope to fall to half its original value
the process by which an unstable atomic nucleus loses energy by radiation
when your phone battery is dying
What is radioactive decay?
a fundamental interaction of nature that acts between subatomic particles of matter
the process by which an unstable atomic nucleus loses energy by radiation
the time taken for the radioactivity of a specified isotope to fall to half its original value
a fundamental force of nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as mesons, and initiates the nuclear fusion reaction that fuels the Sun
What is a strong force?
a fundamental interaction of nature that acts between subatomic particles of matter
a fundamental force of nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as mesons, and initiates the nuclear fusion reaction that fuels the Sun
the rock
What is a weak force?
a fundamental force of nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as mesons, and initiates the nuclear fusion reaction that fuels the Sun
a fundamental interaction of nature that acts between subatomic particles of matter
Caleb, George, and Xavier
What is the Lewis Dot Diagram?
a representation of the valence electrons of an atom that uses dots around the symbol of the element
show electrons orbiting the nucleus of an atom somewhat like planets orbit around the sun
Lewis and Clark's expidition
