2/3/2012 · E) P is an element # 15, therefore it has 15 electrons and 15 protons in the neutral state. P-3 mens that P gained extra 3 electrons, however this would not change the number of protons and…
P (Phosphorus) has an atomic number of 15. Therefore, it has 15 protons. A charge of -3 indicates that it has gained 3 electrons. Therefore, it has 18 electrons. Hope this helps :), The number of electrons in {eq}rm P^{-3} {/eq} = 18 Now, atomic mass = number of protons + number of neutrons 31 = 15 + number of neutrons number of neutrons = 31 – 15 number of neutrons = .
How many protons , neutrons , and electrons does P^3 – have??? Blink your eyes. Was work done? Explain your answer. What statements accurately describe matter? Check all that apply Water has a pH value than baking soda higher lower How many protons , neutrons , and electrons does Al^3+ have?, 6/26/2008 · The mass is the total number of protons plus neutrons . So if this total is 56, and there are 26 protons , the neutrons make up the remainder, which is 30. Finally, since protons have a +1 charge and electrons have a -1 charge, a neutral Fe atom would have equal numbers of protons and neutrons (meaning that it would have 26 electrons as well).
The symbol is for phosphorus having atomic number 15. That means it has in its neutral state.The given symbol has a -3 charge that means it has gained 3 electrons so, the number of electrons in the is: . The number of protons will remain same that is the number of protons = 15.So, the ion has that gives charge on the ion.So, the answer is .
Number of Protons / Electrons : 15 Number of Neutrons : 16 Classification: Non-metal Crystal Structure: Monoclinic Density @ 293 K: 1.82 g/cm 3 Color: white Atomic Structure : Number of Energy Levels: 3 First Energy Level: 2 Second Energy Level: 8 Third Energy Level: 5 Isotopes. Isotope: Half Life: P-31: Stable: P-32: 14.28 days: P-33:, 18 e- 15p. 15 protons is a dead giveaway that we’re dealing with phosphorus (it is atomic number 15). 18 electrons means it has 3 extra (18-15 = 3) electrons , each electron has a -1 charge, so we …
