Station Two: Periodic Table And Elemental Characteristics

1. Each electron shell has a specific number of electrons that can be held in its shell.

True

False

The statement is true because each electron shell in an atom has a specific capacity to hold a certain number of electrons. The first shell can hold a maximum of 2 electrons, the second shell can hold a maximum of 8 electrons, and so on. This arrangement is based on the energy levels of the electrons in an atom.

2. The atomic mass of an element can be found...

Underneath the element's symbol

Above the element's symbol

On the side of the element's symbol

The atomic mass of an element can be found underneath the element's symbol because the atomic mass is a numerical value that represents the average mass of the atoms in a sample of that element. It is usually expressed in atomic mass units (amu) and is located below the element's symbol in the periodic table. This allows for easy reference and comparison of the atomic masses of different elements.

3. Which of the following is the atomic number of this element?

C

6

12

The atomic number of an element represents the number of protons in the nucleus of an atom of that element. In this case, the correct answer is 6, which corresponds to the element carbon.

Explanation

The atomic number of an element represents the number of protons in the nucleus of an atom of that element. In this case, the correct answer is 6, which corresponds to the element carbon.

4. The atomic number of an element provides you with:

The mass of that element

The number of protons in an atom

The number of electrons in an atom

Both B and C

The atomic number of an element provides you with the number of protons in an atom, which is the same as the number of electrons in an atom. This is because in a neutral atom, the number of protons (positive charge) is balanced by the number of electrons (negative charge). Therefore, the correct answer is "Both B and C" as the atomic number provides information about both the number of protons and the number of electrons in an atom.

5. What is the unit for atomic mass?

Grams

Milliliter

Mole

Amu

The unit for atomic mass is amu, which stands for atomic mass unit. This unit is used to measure the mass of atoms and molecules on a very small scale.

6. If you add together the number of ________________________ and number of __________________________ you can calculate an element's atomic mass.

Protons,Nuetrons

Electrons, Atomic Number

Protons,Electrons

Protons,Protons

The correct answer is Protons, Neutrons. To calculate an element's atomic mass, you need to add together the number of protons and neutrons in its nucleus. Protons have a positive charge and determine the element's atomic number, while neutrons have no charge and contribute to the element's mass. Electrons, on the other hand, are negatively charged particles that orbit the nucleus and do not significantly contribute to the atomic mass.
