Chapter 2 Pt 2 Flashcards
An atom that has gained or lost one or more electrons, thus acquiring a charge
Ion
A chemical bond resulting from the attraction between oppositely charged ions.
Ionic bond
A variant form of an atom. The variant form has the same number of protons but different numbers of neutrons.
Isotope
A group of two or more atoms held together by covalent bonds
Molecule
An electrically neutral particle (a particle having no electrical charge), found in the nucleus of an atom.
Neutron
A type of bond in which electrons are shared equally between two atoms of similar electronegativity.
Nonpolar covalent bond
An atom’s central core, containing protons and neutrons.
Nucleus
A measure of the relative acidity of a solution, ranging in value from 0 (most acidic) to 14 (most basic). The letters stand for potential hydrogen and refer to the concentration of hydrogen ions (H+).
pH scale
A type of bond between atoms that differ in electronegativity. The shared electrons are pulled closer to the more electronegative atom, making it slightly negative and the other atom slightly positive.
Polar covalent bond
An item containing polar covalent bonds
Polar molecule
An ending material in a chemical reaction.
Product
A subatomic particle with a single positive electrical charge, found in the nucleus of an atom.
Subatomic particle
A variant form of an element whose nucleus decays spontaneously, giving off particles and energy.
Radioactive isotope
A starting material in a chemical reaction
Reactant
A compound resulting from the formation of ionic bonds; also called an ionic compound.
Salt
