The atomic number of an element is 35. What is the total number of electrons present in all the 'p' orbitals of the ground state of that element?
Correct answer: A. 17
- A. 17
- B. 23
- C. 11
- D. 6
Explanation
To find the total number of electrons present in all the 'p' orbitals of the ground state of the element with atomic number 35, we need to determine the electron configuration of the element. The atomic number of an element represents the number of protons in the nucleus of its atoms. For the element with atomic number 35, Atomic number = Number of protons = 35. Since atoms are electrically neutral, the number of electrons in a neutral atom is also 35. According to Aufbau rule, the elctronic configuration is:1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5. We can calculate the number of electrons in p orbitals by simply adding i.e. 6+6+5 = 17. So, the number of p-orbital elctrons=17

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
