TEAS 2025/2026 - Chemistry exam
40Questions & Correct and Verified
Answers.Latest update2025/2026 Graded A+,
Exams of Nursing
Groups - CORRECT ANSWERS Vertical columns on the periodic table. Atoms are grouped
together into these columns because they share properties, and have the same number of valence
electrons.
Periods - CORRECT ANSWERS Horizontal rows on the periodic table. As you move from left to
right across a __________, the ionization energy increases.
Valence - CORRECT ANSWERS Electrons on the outermost energy level of an atom. To
complete a __________ shell, an atom needs 8 electrons.
Atomic Mass - CORRECT ANSWERS The sum of the masses of protons and neutrons in one
atom of an element
Atomic Number - CORRECT ANSWERS the number of protons in the nucleus of an atom
Anion - CORRECT ANSWERS
Cation - CORRECT ANSWERS
Metal - CORRECT ANSWERS Elements that are good conductors of heat and electric current.
Nonmetal - CORRECT ANSWERS an element that conducts heat and electricity poorly
, Ionic Bond - CORRECT ANSWERS A chemical bond resulting from the attraction between
oppositely charged ions.
Covalent Bond - CORRECT ANSWERS A chemical bond formed when two atoms share electrons
Polar Covalent Bond - CORRECT ANSWERS unequal sharing of electrons due to one atom being
more negatively charged than the other
Nonpolar Covalent Bond - CORRECT ANSWERS equal sharing of electrons
Hydrogen Bond
- H bond only forms with F, O, and N - CORRECT ANSWERS Attraction between a slightly
positive hydrogen atom and a slightly negative atom.
Compound - CORRECT ANSWERS A substance made of two or more elements
Density - CORRECT ANSWERS
Solids - CORRECT ANSWERS In _______, the molecules are packed together in a tight, orderly
pattern. _______ have a definite shape and volume.
Liquids - CORRECT ANSWERS The molecules in _________ are less ordered and exhibit both
translational and vibrational motion. _________ have a definite volume, but don't have shape (They
take the shape of their container).
Gases - CORRECT ANSWERS ____ molecules are rapidly moving and spread far apart. _____
havre no definite shape nor volume.
