Based on electronic configuration, the possible number of total electrons in atom with three electrons in its valence shell is 13, option A.
What is the possible number of total electrons in atom with three electrons in its valence shell?
The arrangement of electrons in an atom is known as electronic configuration.
Based on electronic configuration;
- the first shell can contain two electrons
- the second shell can contain 8 electrons
- the next shell can contain 18
Thus, if we removes the first ten electrons, from each option, The one that has 3 valence electrons is option A, 13.
