Chemistry HESI A2 Quizlet

Correct Answer: B

Rationale: The correct answer is B: Non-polar. In a covalent bond where electrons are shared equally, the electronegativity of the atoms involved is the same, resulting in a symmetrical distribution of charge. This leads to a non-polar covalent bond. A: Polar bonds occur when there is an unequal sharing of electrons due to differences in electronegativity. C: Ionic bonds involve the complete transfer of electrons from one atom to another, resulting in charged ions. D: Hydrogen bonds are a type of intermolecular force, not a classification of covalent bonds based on electron sharing.

Correct Answer: A

Rationale: The correct answer is A: Neutrons. Neutrons are neutral particles because they have no charge, unlike protons (positively charged), electrons (negatively charged), and cations (positively charged ions). Neutrons are found in the nucleus of an atom along with protons, contributing to the atomic mass without affecting the overall charge. This makes them essential for maintaining the stability of the nucleus. Therefore, neutral particles are called neutrons.

Correct Answer: C

Rationale: The correct answer is C: Anions. Negatively charged ions are referred to as anions because they have gained extra electrons, resulting in a negative charge. Neutrons (A) are neutral particles found in the nucleus of an atom. Protons (B) are positively charged particles found in the nucleus. Cations (D) are positively charged ions that have lost electrons. Therefore, based on the definition of negatively charged ions, anions are the correct choice.

Correct Answer: A

Rationale: The correct answer is A: Periods. Periods are the horizontal rows in the periodic table that represent the number of electron shells an element has. Each period corresponds to the principal energy level of the element. Families (Choice B) are the vertical columns of the periodic table that share similar properties. Groups (Choice C) are also vertical columns that share similar chemical properties. Columns (Choice D) are not a term used in the context of the periodic table. Therefore, the correct term for the horizontal rows in the periodic table is periods.

Correct Answer: C

Rationale: The correct answer is C: Cations. Positively charged ions are called cations because they have lost electrons, resulting in a net positive charge. Neutrons (A) are neutral particles found in the nucleus, not charged. Protons (B) are positively charged particles in the nucleus but not considered ions. Electrons (D) are negatively charged particles orbiting the nucleus and form anions when gained. Therefore, Cations are the correct answer as they specifically refer to positively charged ions due to electron loss.
