well core electrons is the number of total electrons minus valence electrons so.......Phosphorus has 18 electrons and 5 valence electrons so 18 - 5 = 13 so there are 13 core electrons
the number of protons equal the number of electrons. the element phosphorus has 15 electrons on its outer rings. the energy levels are 2,8,and 5. this element also has 15 protons and neutrons. written by: 8th grade student Kirby
Phosphorus atoms have five valence electrons. You can know this because P is in group 15/VA. The number of valence electrons is the same as the VA group number (5), or group number 15 minus 10, which is 5.
The total number of electrons in Phosphorus (P) is 15 (its atomic number). The first energy level contains 2, the second energy level contains 8, and the third energy level contains 5.
An atom of fluorine has 9 electrons in total. Electrons are equal to protons when the atom isn't an ion, and the number of protons is also the atomic number of the element, so you just need to know the atomic number to find out the number of electrons or protons.
15 protons 18 electrons And I believe roughly 16 neutrons

18. Phosphorus posses 15 electrons and 15 protons, respectively its charge is 0.By accepting 3 more electrons, with their negative charge the total charge of the atom would decrease by 3.So the total charge would be -3 and the total number of electrons would be 18.

If "penultimate" means "next-to-outermost", the correct answer is 8: The innermost shell is full with two 1s electrons; the next-to-outermost shell is full with two 2s electrons and six 2p electrons, for a total of 8. The outermost shell has five valence electrons, constituting with the two inner shells the remainder of the proper number of total electrons for phosphorus, 15, its atomic number.

Phosphorus has to gain a total of 3 electrons to achieve a noble gas configuration. You can find this for any non-metal because the last digit of its group number is the number of valence electrons it has. For example Phosphorus has 5 and Sulfur has 6. In order to achieve a noble gas electron configuration, you must have 8 valence electrons, so phosphorus must gain 3.
There are 15 electrons total, with 5 valence (outer shell) electrons
The total number of electrons in Phosphorus (P) is 15 (its atomic number). The first energy level contains 2, the second energy level contains 8, and the third energy level contains 5.
An Oxygen atom consists of eight electrons. The total number of protons will always match the number of electron.

Phosphorous (P) actually has a total of 15 electrons, but the 3 electrons referred to in the question are VALENCE electrons, i.e. outermost electrons.
