Answer:
The total number so electrons in the valence of an atom is 2.
Explanation:
Atomic number: This is the number which represent the total number of protons in an atom. An atom is electrically neutral which means that number of protons are equal to number of electrons. it is denoted by letter Z.
Z = Number of protons or electrons in an atom
So, atom with atomic number of 14 will have 14 number of protons and 14 number of electrons.
An electronic configuration will given as:
[tex][X]^{14}=1s^22s^22p^63s^23p^2[/tex]
The total number so electrons in the valence of an atom is 2.
