Answer:
Valence electrons in an atom of phosphorus in the ground state are found in 3rd shell.
Explanation:
Phosphorus has an atomic number of 15. Its electronic configuration is 2, 8, 5. This configuration implies that, phosphorus electrons are distributed in three different shells and the number of electrons in the outermost shell, which is the third shell, is 5. The ground state refers to a state, where the atoms of phosphorus are not excited. Electrons move away from their ground states when they are excited.

This is hard to kind of type out description on how I do it for me but here goes. (I’m actually 12 :P) since the angle on the opposite side of the 107* obtuse angles it would also be 107*. On the angle right below angle a it would also be 107* because of opposite angle relationship (I forgot the actual name) For angle a there is a way that I find easy to find the angle, with supplementary angle. There might be another way but this is how I do it. I subtract 180-107 because 180* is a line then I get angle a, 73*. Using that opposite angle thing the angle identical to angle a is also 73, also is the one beside the 107* degree obtuse angle. You add 73+73 (73*2) and get 146. Then subtract 180-146. Hope that was helpful good luck!
A contact force is any force that requires contact to occur. ... Contact forces are often decomposed into orthogonal components, one perpendicular to the surface(s) in contact called the normal force, and one parallel to the surface(s) in contact, called the friction force. Hope this helps you
