Question

for each atomic number below, fill in the table for the name of the element, the number of protons, and the number of electrons. part 1 of 2 atomic number 20 element name number of protons number of electrons

Explanation:

Step1: Determine Element Name

The atomic number is 20. From the periodic table, the element with atomic number 20 is Calcium (Ca).

Step2: Determine Number of Protons

The number of protons in an atom is equal to its atomic number. So, for atomic number 20, the number of protons is 20.

Step3: Determine Number of Electrons

In a neutral atom, the number of electrons is equal to the number of protons. So, the number of electrons is also 20.

Answer:

Element name	Number of protons	Number of electrons
