Outcome #4 Vocabulary (Option 2)

Chem A
Across
Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties.
A category of elements that are typically solid and are hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity.
A column of elements on the periodic table of the elements.
A subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
An outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond.
Pure substance that can be decomposed into two or more elements.
Region around the nucleus of an atom where electrons are more than likely to be found.
A chart of the chemical elements that displays them in rows horizontally in order of increasing atomic number and vertically according to similarity of the chemical properties of their atoms.
A negatively charged ion.
The difference between the mass of an isotope and its mass number.
The total number of protons and neutrons in a nucleus.
A German scientist called Johann Döbereiner put forward his law of triads in 1817. Each of Döbereiner's triads was a group of three elements. The appearance and reactions of the elements in a triad were similar to each other.
A category of elements that tend to be brittle, dull in appearance and good insulators.
Down

Substance that is composed of a single type of atom; a substance that cannot be decomposed by a chemical change.
A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
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.
A positively charged ion.
Trends or recurring variations in element properties with increasing atomic number.
The sum of the masses of an element’s isotopes, each multiplied by its natural abundance.
A shorthand method of representing an element.
The number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
In chemistry, the generalization made by the English chemist J.A.R. Newlands in 1865 that, if the chemical elements are arranged according to increasing atomic weight, those with similar physical and chemical properties occur after each interval of seven elements.
A row of elements on the periodic table of the elements.
An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
Smallest particle of an element that can enter into a chemical combination.
