Atomic number of any element–a)Atomic weight divided by twob)Nuc...
Understanding Atomic Number
The atomic number of an element is a fundamental concept in chemistry and is defined as the number of protons present in the nucleus of an atom. Let's explore the options provided to clarify why option 'C' (Electrical charge of nucleus) was chosen as the correct answer:
Definition of Atomic Number
- The atomic number (Z) is unique to each element and determines its identity.
- It is always equal to the number of protons in the nucleus.
Explanation of Options
- a) Atomic weight divided by two:
- This is incorrect because atomic weight is not directly related to atomic number. Atomic weight is an average mass of an element’s isotopes, not its protons.
- b) Nucleus weight:
- This option is misleading. The nucleus weight refers to the overall mass of protons and neutrons, which does not define the atomic number.
- c) Electrical charge of nucleus:
- This is correct because the nucleus consists of positively charged protons. Therefore, the total positive charge is equal to the atomic number, which is the count of protons.
- d) Total charge of electrons:
- This statement is incorrect since electrons are negatively charged and their total charge is not indicative of the atomic number.
Conclusion
In summary, the atomic number reflects the number of protons in the nucleus, which directly corresponds to the nucleus's positive electrical charge. Hence, the correct answer is option 'C', as it accurately describes the relationship between atomic number and the charge of the nucleus.

Atomic number of any element–a)Atomic weight divided by twob)Nuc...
This is because the atomic number represents the number of protons in the nucleus and each proton carries a positive charge of +1 elementary charge.
Therefore, the electrical charge of the nucleus is directly proportional to the atomic number.
Therefore, the electrical charge of the nucleus is directly proportional to the atomic number.
