59. Each element has an average atomic mass
Each element has an average atomic mass. Why is it called an “average” atomic mass and how is it determined?

60. Each element has an average atomic mass
Each element has an average atomic mass. Why is it called an “average” atomic mass and how is it determined?
It is called an average atomic mass because an element can have different isotopes. Each isotope has a different number of neutrons in its nucleus. Therefore each isotope has a different atomic mass.
The average atomic mass is the weighted average mass of all the isotopes. To find the average atomic mass, each naturally occurring isotope is identified. Each isotope of the element takes up a certain percentage of the element found naturally. These percentages are then used to make a weighted average.

63. Explain the law of conservation of mass.
Give an example.

64. Explain the law of conservation of mass.
The law of conservation of mass states that during a physical or a chemical change, mass is neither created nor destroyed.
Example: vinegar + baking soda = chemical reaction in which a gas is produced. In a closed system (like put a balloon over the beaker/flask) the mass before would equal the mass after. In a open system, the law is still observed, but we are unable to measure. Closing the system is a good way to prove.

65. The element lithium (Li) has an atomic mass of 3 and a mass number of 7.
Explain how you know that the diagram above represents a lithium atom.

66. Explain how you know that the diagram above represents a lithium atom.
The element lithium (Li) has an atomic mass of 3 and a mass number of 7. Explain how you know that the diagram above represents a lithium atom.
The element lithium (Li) has an atomic mass of 3 and a mass number of 7.
Explain how you know that the
diagram above represents a lithium
atom.
The diagram shows an atom that has 3 protons and 4 neutrons. Because the atomic mass of an atom is equal to the number of protons in the atom (3 for lithium) and the mass number of an atom is equal to the number of protons plus the number of neutrons in the atom (7 for lithium), the diagram can be recognized as representing lithium.
