1) Z=17, A=35
2) Z=92, A=233
3) Z=4, A=9​

Answer 1

Answer:

1) 17C^35 (chlorine)

2)92U^233 (Uranium)

3)4Be^9 (beryllium)

Explanation:

they are chlorine, Uranium, beryllium respectively

Answer 2

1) For Z = 17, A = 35 symbol is $_{17}Cl^{35}$.

2) For Z = 92, A = 233 symbol is $_{92}Cl^{233}$.

3) For Z = 4, A = 9​ symbol is $_{4}Cl^{9}$.

Explanation:

Atomic number is the sum of total number of protons present in an atom. Whereas atomic mass is the sum of total number of protons and neutrons present in an atom.

Chlorine is the element which has atomic number 17 and atomic mass 35. It is represented as $_{17}Cl^{35}$.

Uranium is the element which has atomic number 92 and atomic mass 233. It is represented as $_{92}Cl^{233}$.

Beryllium is the element which has atomic number 4 and atomic mass 9. It is represented as $_{4}Cl^{9}$.
