Question 2: What is the term used to describe the distance or number of units a
number is from zero, which is always positive?
Choices:
1) Absolute value 2) Negative value 3) Reciprocal 4) Exponent
Correct Answer: Absolute value
Explanation: Absolute value represents the non-negative distance of a number from zero on a number line.
Question 3: Division of any number by zero results in a value known as what?
Choices:
1) Zero 2) In�nity 3) Unde�ned 4) Negative one
Correct Answer: Unde�ned
Explanation: In mathematics, division by zero has no meaningful de�nition and is classi�ed as unde�ned.Page 2
Question 4: How many protons and electrons are found in a neutral atom of
Hydrogen?
Choices:
1) 2 protons and 2 electrons 2) 1 proton and 2 electrons 3) 1 proton and 1 electron 4) 2 protons and 1 electron
Correct Answer: 1 proton and 1 electron
Explanation: A standard, neutral hydrogen atom consists of exactly 1 proton and 1 electron.Question 5: A neutral copper atom is composed of which speci�c subatomic particle distribution?
Choices:
1) 29 protons, 35 neutrons, and 29 electrons 2) 29 protons, 29 neutrons, and 35 electrons 3) 35 protons, 29 neutrons, and 35 electrons 4) 35 protons, 35 neutrons, and 29 electrons
Correct Answer: 29 protons, 35 neutrons, and 29 electrons
