GENERAL KNOWLEDGE

Detailed explanation-1: -If an atom has 35 protons, it also indicates that the element’s atomic number is 35. Because the atomic number is also defined by the number of protons. This implies that there are 35 electrons orbiting the nucleus. As a result, the correct answer is 35.

Detailed explanation-2: -Bromine has an atomic number of 35, and so has 35 protons. You are told that the mass number is 79, and so there are a total of 79 protons plus neutrons.

Detailed explanation-3: -Each orbital holds two electrons which differ in a property known as spin. Orbital: A region of space within an atom where an electron in a given subshell can be found. Any orbital can hold a maximum of 2 electrons with opposite spin.

Detailed explanation-4: -Answer and Explanation: The atomic number represents the number of protons, which is also equal to the number of electrons in neutral (no electric charge) atoms. Therefore, the given atom has 35 protons because the atomic number is 35 (this is the element Bromine).

Detailed explanation-5: -If the atom is neutral (uncharged), then the number of electrons must be equal to the number of protons. Therefore, the atom of this isotope contains 32 electrons.
