Matter and Change - $20 Which of the following is not a chemical change? a) gas burning in a car b) rust forming on an iron nail c) a precipitate forming from two solutions d) water boiling to turn to a gas d

Matter and Change - $40 What is mass? A count of the amount of matter an object contains

Matter and Change - $60 Elements, Compounds, Mixtures Substances that cannot be broken down are Substances broken down by chemical changes are Substances broken down by physical changes are Elements, Compounds, Mixtures

Matter and Change - $80 What is the difference between a solution and a heterogeneous mixture? Solution = homogeneous mixture = uniform composition; can’t see different parts Heterogeneous mixture = nonuniform composition = can see different phases

Matter and Change - $100 Name the techniques needed to separate a mixture of iron, sand, water, and rubbing alcohol Magnet = separate out iron Filtration = separate out sand Distillation = separate the two liquids

Atomic Structure - $20 The atomic mass of P is 30.97 amu. What is the most common isotope of P? P-31

Atomic Structure - $40 Match Protons determine A. atom’s mass Electrons determine B. atom’s identity Neutrons determine C. atom’s charge B C A

Atomic Structure - $60 The electron configuration of Co (long and short) 1s22s22p63s23p64s23d7 [Ar] 4s23d7

Atomic Structure - $80 The 5 atomic models discussed (scientist name and model name) Dalton – the atom Thompson – plum pudding Rutherford – the nuclear atom Bohr – Bohr’s model of the atom Schrodinger – electron cloud

Atomic Structure - $100 Chlorine has 2 isotopes. Cl-35 occurs 22.5% and Cl-37 occurs 77.5%. What is the atomic mass of Cl? Atomic Mass = (Mass Number)(%) + (Mass Number)(%) Atomic Mass = (35)(.225) + (37)(.775) Atomic Mass = 35.45 amu

The Periodic Table - $20 Element with highest electronegativity: Element with biggest atomic radius: Element with highest ionization energy: F, Fr, F

The Periodic Table - $40 Elements in the same group of the periodic table behave similarly (have similar chemical and physical properties) because they all have the same number of valence electrons

The Periodic Table - $60 A vertical column on the periodic table is called a A horizontal row on the periodic table is called a The element in group 1, period 2 is Group or family Period Li

The Periodic Table - $80 Group 2 aka Group 17 aka Group 18 aka Alkali Earth Metals Halogens Noble Gases

The Periodic Table - $100 The step line separates Give an example of a metal, semimetal, and nonmetal Metals from nonmetals Metal = Anything to the left of stepline and Al Nonmetal = Anything to the right of stepline Semimetal = Anything touching (above and below) stepline

Bonding - $20 The octet rule says… atoms gain, lose, or share electrons to get the electron configuration of a noble gas

Bonding - $40 Name 2 exceptions to the octet rule H(2), He(2), Be(4), B(6), anything with a d orbital (up to 12)

Bonding - $60 What type of elements are in an ionic bond? What type of elements are in a covalent bond? Ionic = Metal + Nonmetal Covalent = 2 nonmetals

Bonding - $80 Describe how the electrons are acting differently in an ionic vs a covalent bond Ionic bond = transfer (one atom’s loss and one atom’s gain) of electrons Covalent bond = sharing of electrons between 2 atoms

Bonding - $100 Order the following things from strongest to weakest: Single bond Hydrogen bond Ionic bond Double bond Dipole-dipole Triple bond dispersion (strongest) Triple bond Double bond Single bond Ionic bond Hydrogen bond dipole-dipole dispersion (weakest)

Ions - $20 Name an element that can naturally form multiple ions (can have ions with different charges) Any transition metal

Ions - $40 State the charges of the following elements: Mg P Cl Na

Ions - $60 Are the following things ionic or molecular compounds? N2O4 FeSO4 C2H3O2-1 Molecular Ionic

Ions - $80 What are the ions in the following compound? CuSO4 Cu+2

Ions - $100 How many protons, electrons, and neutrons are in the following ions? Ca+2 P-3 Ca+2 = 20p, 18e, 20n P-3 = 15p, 18e, 16n
