Periodic Table Basic
Atoms with different numbers of neutrons in their atomic nuclei of the same substance.
What is an isotope?
The amount of matter an object contains
Mass
Matter is never created or destroyed, but it can change.
What is a The Law of Conservation of Matter?
An atom or molecule that has gained or lost electrons to gain or lose an electrical charge.
What is an ion?
The exchange of a pair of electrons forms a very tight chemical bond.
What is a covalent bond?
(+) charged atom
What is a proton?
Anything that has mass and takes up space
Matter
The charge an atom has after it has given or taken an Electron
What is an Oxidation number?
A calculation of the attraction that an element's atoms have for electrons.
What is Electronegativity?
When one atom passes electrons to another and a positively charged ion forms a bond with a negatively charged ion
What are ionic bonds?
(-) charged atom
What is an electron?
The total mass of an element's atoms.
What is Atomic Mass?
The rule that defines atoms' preference for having eight electrons in their valence shell.
What is the octet rule?
A substance produced by combining elements in unique proportions in a chemical reaction/When two or more substances are mixed, but not chemically/A material produced as a result of a chemical reaction.
What are compounds, products, and mixtures?
A weak bond formed between two molecules by the presence of a proton in one and an electronegative atom in the other.
What are hydrogen bonds?
Neutral atom/No charge
What is a neutron?
Anion
What is a negatively charged ion?
A calculation of the attraction that an element's atoms have for electrons
What is electronegativity?
Electrons that can participate actively in chemical reactions
What is a Valence Electron?
The number of protons in an atomic nucleus.
What is an Atomic Number?
