What is the name of Zn₃(PO₄)₂?

What is the formula for barium hydroxide?

As you increase the atomic number in a group the atomic radii

the study of chemicals, their properties, and the reactions in which they are involved

What is the sum of the oxidation numbers in a neutral compound?

manmade, created elements; 94 and higher on the periodic table

Name the following: P₂O₅ (covalent)

A homogeneous mixture can be separated by all EXCEPT

state of matter in which a material has a fixed volume but a variable shape

the property that allows a metal to be squeezed or drawn out into a wire

What is the of CuCO₃?

the weighted average of the atomic masses of an elements naturally occurring isotopes

What is the mass number of this atom?

Which is a chemical change?

a nuclear particle with virtually no mass which has a negative charge; found outside the nucleus

³⁵Cl has

a chemical bond resulting from the electrostatic attractive force between positive and negative ions;

atoms of the same element with differing numbers of neutrons and therefore different mass numbers

Which elements are good conductors of heat, ductile, malleable, and mostly solid at room temperature?

electrons in the highest energy level

Which element has the greatest electronegativity?

How many electrons go in the S, P, D, and F sublevel?

horizontal row of blocks on the periodic table

a chemical bond in which shared electrons have an unequal attraction; a positive and negative region forms

Carbon has an electron configuration of 1s² 2s² 2p^2. How many more electrons does carbon need to satisfy the octet rule?

Chlorine, bromine, and iodine are

Express 7350 in scientific notation

As the electronegavitity difference between two bonded atoms increases, the bond becomes more

Italian salad dressing, soil, and gravel are example of a(n)

a neutral group of atoms held together by covalent bonds

a nuclear particle that has about the same mass as a proton but with no electrical charge

Which is WRONG?

elements transfer or share valence electrons in order to fill their S and P sublevel (8)

As you go across a period from left to right, the first ionization energy

In the modern periodic table, elements are ordered according to

A substance composed of two or more elements combined chemically in a fixed proportion by mass

Which was one of Rutherford's conclusions?

Convert to scientific notation:

the ability of a metal to be hammered into a thin sheet

a chemical bond in which electrons are shared equally; occurs between identically bonded atoms

What are isotopes

 state of matter in which a material has a variable shape and volume
