Monatomic ions - Study guides, Class notes & Summaries

molecular mass (molecular weight) correct answer: the sum of the atomic masses, in atomic mass units, of all the atoms in the formula of a compound empirical formula correct answer: a chemical formula showing the ratio of elements in a compound rather than the total number of atoms Avogadro's number (Mole) correct answer: 6.02 x 10^23 proton correct answer: A subatomic particle that has a positive charge and that is found in the nucleus of an atom neutron correct answer: A suba...

General Chemistry 1- Polyatomic Ions | Latest Update | 2024/2025 | 100% Correct What are polyatomic ions, and how do they differ from monatomic ions? Polyatomic ions are ions composed of two or more atoms covalently bonded together, carrying a net charge. They differ from monatomic ions, which consist of only a single atom with a charge. What is the charge and composition of the sulfate ion? The sulfate ion has a charge of -2 and is composed of one sulfur atom covalently bonded to ...

Hypothesis vs Theory vs Law - Answer-Hypothesis: If, then, because Law: Statement or equation about a relationship - ex: force = mass * gravity Theory: Explains why a law exists Law of Conservation of Mass - Answer-Mass is always constant - Reactant mass = Product mass They are used (upheld) in chemical equations Three common states of matter and their characteristics - Answer-- Solid (s): color - Liquid (aq): melting point, solubility - Gas (g): Difference between Elements, Compounds,...

Crystalline solid : a solid made of an ordered array of atoms, ions, or molecules Amorphous solid : a solid that lacks long-range order for the atoms, ions, or molecules in its structure Molecular solid : a solid formed by neutral, covalently bonded molecules held together by IMFs Ionic solid : a solid consisting of monatomic or polyatomic ions held together by ionic bond

Metal atoms can ________ electrons in chemical reactions to form cations. - ANSWER-lose Nonmetal and metalloid elements can _____ electrons to form anions. - ANSWER-gains Ion-Ion forces... - ANSWER-apply to very high temperature liquids and to ionic solids, and are due to net attraction between + & - charges; usually stronger than forces between molecules. The greater the charge of ion-ion forces, the __________ the attraction. - ANSWER-stronger The greater the distance of ion-ion fo...

Alloy - A mixture of two or more metals Amorphous solids - a solid that lacks order and has random or disordered arrangements of particles Atomic solids - A solid formed by the weak attraction between noble gas atoms covalent network solid - A solid formed by covalent bonds among nonmetal atoms in an extended array. Crystal lattice - A 3-dimensional geometric arrangement of the atoms or molecules or ions composing a crystal Crystal structure - the arrangement of atoms, ions, or molecules...
