• Atomic no. of Fluorine is $9$ Which is given atomic no.
• Also, the symbol of Fluorine is $F$

Therefore, The required element is Fluorine and its symbol is, $F$

Part (c) Step 1: Given Information

We need to write the names and the symbols of the elements having atomic number $20$

Part (c) Step 2: Explanation

We know that, 

• Atomic no. of Calcium is $20$ Which is given atomic no.
• Also, the symbol of Calcium is $Ca$

Therefore, The required element is Calcium and its symbol is, $Ca$

Part (d) Step 1: Given Information

We need to write the names and the symbols of the elements having atomic number $30$.

Part (d) Step 2: Explanation

We know that, 

• Atomic no. of Zinc is $30$ Which is given atomic no.
• Also, the symbol of Zinc is $Zn$

Therefore, The required element is Zinc and its symbol is, $Zn$

Part (e) Step 1: Given Information

We need to write the names and the symbols of the elements having atomic number $10$

Part (e) Step 2: Explanation

We know that, 

• Atomic no. of Neon is $10$ Which is given atomic no.
• Also, the symbol of Neon is $Ne$

Therefore, The required element is Neon and its symbol is, $Ne$

Part (f) Step 1: Given Information

We need to write the names and the symbols of the elements having atomic number $14$

Part (f) Step 2: Explanation
