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