Substances that contain atoms that are all the same are called
- A.
  
  Elements
- B.
  
  Compounds
- C.
  
  Mixtures
Correct Answer
A. Elements

Explanation
Elements are substances that contain atoms that are all the same. Each element is made up of atoms with the same number of protons in their nucleus. These atoms cannot be broken down into simpler substances through chemical reactions. Examples of elements include oxygen, carbon, and gold. Compounds, on the other hand, are substances made up of two or more different elements chemically combined. Mixtures are combinations of different substances that are physically mixed together but not chemically bonded.

Compounds are substances that are made of
- A.
  
  One type of atom
- B.
  
  Two or more different types of atoms
Correct Answer
B. Two or more different types of atoms

Explanation
Compounds are substances that are made up of two or more different types of atoms. This means that in order for a substance to be considered a compound, it must consist of atoms from at least two different elements. This is because compounds are formed through chemical bonding between different elements, resulting in the creation of a new substance with unique properties. Therefore, the correct answer is "two or more different types of atoms".

Sodium (Na) is considered an element while sodium chloride (NaCl) is considered a compound. This is because of sodium chloride
- A.
  
  Is a solid at room temperature
- B.
  
  Is used to flavor foods
- C.
  
  Is made from two different elements
- D.
  
  Is made from the same types of atoms
Correct Answer
C. Is made from two different elements

Explanation
Sodium chloride (NaCl) is considered a compound because it is made from two different elements, sodium (Na) and chlorine (Cl). Compounds are formed when two or more different elements chemically combine together. In the case of sodium chloride, sodium and chlorine atoms combine in a fixed ratio to form a stable compound with distinct properties. Sodium, on the other hand, is considered an element because it consists of only one type of atom.

What is the difference between CO and Co?
- A.
  
  CO is made from one type of atom
- B.
  
  CO is an element and Co is a compound
- C.
  
  Co is made from two types of atoms
- D.
  
  CO is a compound and Co is an element
Correct Answer
D. CO is a compound and Co is an element

Explanation
CO is a combination of the two elements Carbon (C) and Oxygen (O). Co is the symbol for the element Cobalt. Remember, there are no elements with two capital letters as a symbol.

How many atoms of nitrogen are in NH₄?
- A.
  
  0
- B.
  
  1
- C.
  
  4
- D.
  
  5
Correct Answer
B. 1

Explanation
When a symbol in a chemical formula (in this example N for Nitrogen) does not have a little number in front of it, there is only one atom of that element.

Which of the following elements would be malleable?
- A.
  
  Carbon (C)
- B.
  
  Iron (Fe)
- C.
  
  Option 3
- D.
  
  Option 4
Correct Answer
B. Iron (Fe)

Explanation
Metals are malleable or easy to bend. Iron (Fe) is found on the left side of the Periodic Table so it is a metal.

- A.
  
  Potassium (K)
- B.
  
  Platinum (Pt)
- C.
  
  Phosphorus (P)
- D.
  
  None
Correct Answer
C. Phosphorus (P)

Explanation
Nonmetals are brittle or easy to break. Phosphorus is on the right side of the Table and is, therefore, a nonmetal.
