The missing characteristics (values) of each chemical element are:
A = 20
B = 40
C = Ca
D = 10
E = 9
F = F
A periodic table is defined as an organized tabular arrangement of all the chemical elements in order of increasing atomic number (number of protons) and in multiple rows.
In this exercise, you're required to find or solve for the missing characteristics (values) of each chemical element and describe each atom by using the attached periodic table.
Note:
- Atomic number is the same as the number of protons.
- [tex]Mass \; number = number \; of \; protons + number \; of \; neutrons[/tex]
- [tex]Number \; of \; neutrons = Mass \; number - number \; of \; protons[/tex]
For Element 1:
A = 20; This is simply because the number of protons is equal to 20.
[tex]Mass \; number = 20 + 20[/tex]
Therefore, the mass number, B = 40.
The chemical element with an atomic number of 20 and a mass number of 40 is Calcium. Also, the chemical symbol of Calcium is Ca.
Therefore, C = Ca.
For Element 2:
[tex]Number \; of \; neutrons = 19 - 9[/tex]
Therefore, the number of neutrons, D = 10.
E = 9; This is simply because the number of protons is equal to 9.
The chemical element with an atomic number of 9 and a mass number of 19 is Florine. Also, the chemical symbol of Calcium is F.
Therefore, F = F.
