What is the name of element number 1?
Hydrogen

What element has the symbol K?

Potassium

How many electrons fit on the first energy level?
2
200

How do you figure out the number of neutrons?

Subtract the atomic number from the atomic mass

200
What particle has a positive charge?
Proton

While moving down in a group, the metallic character 

  1. Increases
  2. Decreases
  3. Remains constant
  4. First increases than decreases.

As we move down the group, the number of shells increases, and thus losing electrons becomes easy for an atom. Thus, the metallic character increases down the group.

Which elements have only one electron?

Hydrogen

How many electrons fit on the third energy level?
18
300
How do you find an element's atomic mass?
Add the number of neutrons and the number of protons together
300
What particle has no charge?
Neutron
300

The only liquid transition metal

Hg is the symbol for the element mercury, which is the only liquid transition metal at room temperature.

Put a cross (X) next to the sentence that is incorrect.

1- the group of the periodic table contain elements that are completely different from each other.

2- All the elements in Groups 2 and 7 are quite reactive.

3- Elements in Group 0 are gases that never take part in chemical reactions. 

1- the group of the periodic table contain elements that are completely different from each other.

400

(True or False )

The symbol for an element is always the first letter of its name.

False

400

Why do all the elements of the same group have similar properties?

All the same group elements have similar properties because they have identical valence electrons.

500
What does the term 'valence electrons' mean? (2 things)
number of electrons on outermost shell, tells how reactive an element is
500

Which of the following CORRECTLY describes the modern periodic table?

1- It has 18 groups and 8 periods

2- It has 18 groups and 10 periods

3- It has 18 groups and 7 periods

4- It has 8 groups and 7 periods

3- It has 18 groups and 7 periods
