Teas test Study Guide Questions and Correct
Answers
1). Intergers
Ans: whole numbers and their opposites no decimals or fractions
2). Factors and multiples
Ans: FACTORS- factors are the two numbers being multiplied in a multiplication
problem. A prime factorization is when you take a number and break it down into factors
over and over until the last numbers are all prime (only divisible by 1 and itself).
MULTIPLES- Multiples are the result of multiplying a certain number by integers.
3). Prime numbers
Ans: a number which can only be divided by itself and 1 which are:
2,3,4,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,87,89,97
4). Prime factorization
Ans: First factor the number then find and pull out the numbers that are prime
5). Pemdas "order of operations"
Ans: Please Excuse My Dear Aunt Sally (Parenthesis, Exponents, Multiply, Divide, Add,
Subtract); order in which an equation is worked out - multiplication and division as well
as adding and subtracting can be interchanged, depending on which comes first (from
left to right) in the equation
6). Gcf (greatest common factor)
Ans: the greatest number that is a factor of two or more numbers

, 7). Lcm (least common multiple)
Ans: The smallest whole number greater than 0 that is a common multiple of each of
two or more numbers.
8). Rules if exponents
Ans: Must always share a base
1. When multiplying you add the exponents
2. When diving you subtracts the exponents
3. A number raised to a fraction power is the same as the root or radical
9). Perfect square
Ans: These are 1,4,9,25,36,49,64,81,100
10). Factorials (e.g. 8!)
Ans: To find the factorial of any integer, multiply it by every positive integer below it,
e.g.:
8x7x6x5x4x3x2x1
Ans: Atoms with the same number of protons but different numbers of neutrons
24). Atomic weight
Ans: Average of the mass numbers of all isotopes (usually 2x the atomic number)

, 25). The atomic nucleus
Ans: The central part of an atom that contains both protons and neutrons.
26). Atomic energy states
Ans: All atoms strive to thrive lowest energy state
27). The n shells
Ans: Energy levels where the electrons are found, the lowest energy leve
28). Orbitals/shells
Ans: regions around the nucleus in which given electron or electron pair is likely to be
found ex) 1s which can only hold 2 electrons
29). P orbital
Ans: 6 electrons
30). Electron configuration
Ans: the arrangement of electrons of an atom in its ground state into various orbitals
around the nuclei of atoms ex) N= 1s2, 2s2, 2p3
31). Valance electrons
Ans: electrons in the outermost energy level These participate in chemical reactions
32). The octet rule
Ans: States that atoms lose, gain or share electrons in order to acquire a full set of
eight valence electrons
33). Transition metals (groups 3-12)
Ans: good thermal conductors, shiny, electric conductors, higher density and melting
points than group and low specific heat, and can be shapes and stretched
