Correct: Atom: smallest basic unit of matter, The charge of a neutron is neutral, Elements can be broken down into simpler substances. , element+element=compound, An ion occurs when an atom loses/gains an electron, NaCl (Sodium Chloride) is an example of a ionic bond, A covalent bond occurs when atoms share electrons, A molecule is 2+ atoms bonded covalently, A solution is a mixture of substances that is the same entirely, The solvent is the substance that exists in a larger amount in a solution and does the dissolving, A solute is what is dissolved, Opposite charges of polar molecules can interact to form hydrogen bonds , This is an example of cohesion., Roots uptake water through adhesion., Acids release protons (H+), Bases remove H+ ions from solutions , Acidity is measured by the pH scale, Incorrect: atom: part of a compound, The charge of a neutron is +, Elements cannot be broken down into simpler substances., atom+atom=compound, An ion occurs when an atom joins an atom, NaCL (Sodium Chloride) is an example of an covalent bond, A covalent bond occurs when atoms lose electrons, A molecule is 2+ electrons bonded together, covalently, A solvent is a mixture that is the same throughout, The solvent is what dissolves, a solute is what does the dissolving in a solution, Opposite charges of polar atoms can interact to form hydrogen bonds , This is an example of adhesion, Roots uptake water through cohesion., Bases release protons (H+), Bases add H+ ions from solutions , Acidity is measured by the Richter scale,
