100
a proton
What is one of the subatomic particles that makes up the nucleus of an atom.
100
A substance that cannot (ordinarily) be broken down into a simpler substance. Consists of only one type of atom.
What is an element.
100
They're insignificant, (like a tic-tac).
What is the reason electrons are not considered in the atomic mass.
100
The way elements are arranged on the periodic table of the elements.
What is by atomic number.
100
The amount of time it takes for a radioactive isotope to decay half its mass away.
What is a half-life.
200
electron
What is the subatomic particle with a negative charge responsible for chemical reactions.
200
The number of protons in the nucleus of an atom.
What is the atomic number.
200
Negatively charged subatomic particles.
What is an electron.
200
The most electronegative element on the PTE.
What is Flourine.
200
Anything that has mass and takes up space.
What is matter.
300
Neutron
What is the subatomic particle without a charge that makes up half the nucleus of an atom.
300
Very reactive, and aggressive, they really want electrons.
What is a halogen.
300
A negatively charged ion.
What is an anion.
300
The element with the greatest atomic radius.
What is francium.
300
Subtract the atomic mass from the atomic number.
What is the way to calculate the number of neutrons.
400
Isotope
What is an atom with more or less neutrons than protons. Often unstable.
400
Group 1A, one electron in the valence. Often bond with elements from 7A.
What is an alkali metal.
400
A positively charged ion.
What is a cation.
400
Totally inert, and unwilling to react with other elements. (Like a hipster).
What is a noble gas.
400
Except for hydrogen, it is the number of electrons, protons, and neutrons an atom has. (If the atom isn't an ion or isotope).
What is the atomic number.
500
A quark
What is the subatomic particle that that makes up protons and neutrons.
500
The outermost layer of an atoms electrons, responsible for bonding. Often the same as the group number.
What is valence electrons.
500
Formed when an electron is lost or gained.
What is an ion
500
A vertical arrangement of elements with similar characteristics.
What is a group.
500
Because they are an average of all the isotopes of the atom.
What is the reason atomic masses are not exactly double the atomic number.
