In an atom, there must be the same number of electrons and protons in order for it to be neutral. So, if this atom is neutral and has 15 electrons it must have 15 protons as well.
The number of protons is specific to each element. That is, every atom of an element has the same number of protons, and no two elements have the same number of protons in their atoms. So, there is only one element with 15 protons, and that element is Phosphorus. I found this by looking at the number in the periodic table.
The number of protons is equal to the number next to each element. Hydrogen has 1 proton, helium has 2, lithium has 3 and etc. The 15th element listed on the Periodic Table is Phosphorus, and therefore the answer is phosphorus.

What is the number of electrons in a neutral atom of an element on an periodic table?
There is none, but a neutral atom is called a neutron. There is no neutral element.
An element has an atomic number of 30 how many protons and electrons are in a neutral atom of the element?
It will have 30 protons and 30 electrons if the atom is neutral.
How do you find the number of protons or electrons in a neutral atom of an element?
The number of protons in an atom is equal to the atomic number of the element, which can be found on the periodic table. Since atoms are electrically neutral, the number of electrons in a neutral atom is also equal to the number of protons.
What element has 17 electrons in a neutral atom?
I believe it is Chlorine? Please correct me if I'm wrong.
If element X has 72 protons how many electrons does it have electrons?
Element X with 72 protons will have 72 electrons in a neutral state. The number of protons in an element is equal to the number of electrons in that element's neutral atom.
What is the number of electrons in a neutral atom of an element on an periodic table?
There is none, but a neutral atom is called a neutron. There is no neutral element.
An element has an atomic number of 30 how many protons and electrons are in a neutral atom of the element?
It will have 30 protons and 30 electrons if the atom is neutral.
If you know the number of electrons in a neutral atom can you determine what the element is?
Yes, in a neutral atom the number of electrons and protons is equal, and it is the number of protons that determines what element the atom is. So, by looking at the number of electrons you can tell what element it is.
What number of an element can be used to determine the number of electrons in an atom?
The atomic number of an element can be used to determine the number of electrons in an atom. It is equal to the number of protons in the nucleus of an atom, which also corresponds to the number of electrons in a neutral atom.
What element has eighteen electrons?
As a neutral atom (When it is not an ion) the element argon has eighteen electrons.
What is the element whose atom has 8 electrons when neutral?
The number of electrons corresponds to the "index" number of the element in the periodic table. The 8th element is Oxygen, which has 8 atoms when neutral. That didnt answer the question. ANSWER Neon has 8 electrons :)
Is it true that the number of electrons in an element is the same for all neutral atom of that element?
Yes, this is true for electrons (and protons) of all neutral atoms of an element.
A chloride ion has the same number of electrons as a neutral atom of what element?
A chloride ion (Cl-) has the same number of electrons as a neutral atom of the element argon (Ar).
How do you find the number of protons or electrons in a neutral atom of an element?
The number of protons in an atom is equal to the atomic number of the element, which can be found on the periodic table. Since atoms are electrically neutral, the number of electrons in a neutral atom is also equal to the number of protons.
What number of electrons in a neutral atom of an element will be equal to?
The amount of electrons is balanced by the same amount of protons in a neutral atom, such as for the neutral hydrogen atom; it has 1 proton and 1 electron.
What element has 17 electrons in a neutral atom?
I believe it is Chlorine? Please correct me if I'm wrong.
What element is metallic 29 electrons?
The neutral atom of copper has 29 electrons.
