WebJun 13, 2024 · Both nitrogen and phosphorus have 5 valence electrons, but nitrogen has valency of 3 while phosphorus has valency of 3 or 5. Why is this so? Maybe phosphorus … WebApr 11, 2024 · Explanation: phosphorus has atomic number 15, and is in group 5 and period 3 of the Periodic Table. it is in period 3, because it has orbits at 3 energy levels. there are 2 electrons at the first energy level, and 8 at the second energy level. there are 15 electrons in total, there must be 5 electrons at the third energy level.

WebApr 28, 2024 · Oxygen is found in Period 2, Group 16. Apply the rule of the periodic table to your element. The rule is as follows: If an element is not a transition metal, then valence electrons increase in number as you count groups left to right, along a period. Each new period begins with one valence electron. Exclude groups 3 through 12. Web15 hours ago · Since hydrogen has one valence electron, and phosphorous has three, so P is the central atom in the molecular structure of this compound. Three valence electrons of phosphorous forms pairs with three valence electrons from the hydrogen atoms. The remaining two unpaired electrons of phosphorous are placed on the 4th side that forms a … WebThe valencies of the elements belonging to the s-block and the p-block of the periodic table are generally calculated as the number of valence electrons or eight minus the number of valence electrons. For the d-block and f-block elements, valency is determined not only on the basis of valence electrons but also on d and f orbital electrons. fish farm jobs near me
