Question

protons neutrons number number (symbol) a 7 16 c d 20 56 f using the periodic table, complete the table to describe each atom. type in your answers. a b c d e f

Explanation:

Step1: Determine the atomic number (number of protons) for the first atom

The symbol \( C \) represents carbon. From the periodic table, the atomic number of carbon is \( 6 \). So, the number of protons \( A = 6 \).

Step2: Determine the number of electrons (B)

For a neutral atom, the number of electrons equals the number of protons. Since \( A = 6 \), \( B = 6 \).

Step3: Determine the number of neutrons (E) for the second atom

The number of protons \( D \) (atomic number) can be found from the periodic table. The symbol \( F \) is not given clearly, but if we assume it's calcium (\( Ca \)) (since atomic number \( 20 \) from the number of electrons). The mass number \( = 56 \). Using the formula \( \text{Mass number}=\text{Protons}+\text{Neutrons}\), we have \( 56=20 + E\). Solving for \( E \), we get \( E=56 - 20=36 \).

Answer:

A \( 6 \)
B \( 6 \)
C \( C \) (already given in the symbol column for the first row, but if we follow the order of filling, for the first - row atom with \( 6 \) protons, symbol is \( C \))
D \( 20 \) (atomic number of calcium)
E \( 36 \)
F \( Ca \) (calcium has atomic number \( 20 \))
