The periodic table was originally arranged in order of atomic mass. We now know that it is the electron arrangement that determines how the elements react. Which of the following is the correct description of how you work out the electron arrangement of the first 20 elements?
0%
There can be up to 8 electrons in each energy level (shell)
0%
There must be 8 electrons in every energy level (shell)
0%
There is a maximum of 2 in the first energy level (shell) and up to 8 in the rest
0%
You can have up to 4 in the first energy level (shell) and 8 in the others
Q.2.
Where do you find the metals and non-metals in the periodic table?
0%
Metals on the right, non-metals on the left
0%
Non-metals in the middle surrounded by the metals
0%
Metals in the middle surrounded by the non-metals
0%
Metals on the left, non-metals on the right
Q.3.
Which of the following statements best describes the elements in a period?
0%
The elements in a period have different chemical properties
0%
The elements in a period have the same chemical properties
0%
The elements in a period have similar chemical properties
100%
The elements in a period are inert
Q.4.
