Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
Any atom should have equal number of protons and electrons. If the atom contains 15 protons then it must contain 15 electrons.
Protons are particles with a positive charge, and in order for your atom to be neutral the positive charge must be cancelled out by adding negative charges of the same value. Electrons are negatively charged. So adding 15 electrons to 15 protons would result in a neutral atom. Also since your atom contains 15 protons it must be Phosphorus, element number 15.
15 protons. Also usually 15 electrons and 15 neutrons.
A phosphorus atom has 15 electrons.
An atom of antimony has 5 outer shell electrons. Antimony is in group 15 of the periodic table, so it has 5 valence electrons.
Any atom should have equal number of protons and electrons. If the atom contains 15 protons then it must contain 15 electrons.
The atom also has 15 electrons.
In an atom is neutral and has 15 electrons, then it also has 15 protons and therefore the atomic number is 15.
Protons are particles with a positive charge, and in order for your atom to be neutral the positive charge must be cancelled out by adding negative charges of the same value. Electrons are negatively charged. So adding 15 electrons to 15 protons would result in a neutral atom. Also since your atom contains 15 protons it must be Phosphorus, element number 15.
phosphorus have 15 electron because you know the atomic number to know electron
If the atom is neutral, then it will have 15 electrons to balance the 15 protons.
One phosphorus atom contains 15 protons and 15 electrons, giving it an atomic number of 15.
An atom with 15 protons, 15 neutrons, and 15 electrons.
15 protons. Also usually 15 electrons and 15 neutrons.
There are 15 electrons in a phosphorus atom, but only if it is neutral. The element phosphorus, a nonmetal, is not found free in nature because it is reactive and has loaned out two or more electrons. It has a number of oxidation states ranging through 2, 3, 4 and 5 (and also a -3). The number electrons in a given phosphorus atom will vary depending on its chemical circumstances.
The neutral atom of phosphorus has 15 electrons in the atom.
