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.
What else can I help you with?
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.
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.
What can be said of the number of electrons of the one element can have?
A neutral atom of an element will have the same number of electrons as protons (atomic number). For example, the element magnesium has the atomic number 12, which means that a neutral magnesium atom will have 12 protons and 12 electrons.
The number of electrons in an atom of an element is the same as the element's?
The number of electrons in an atom of an element is the same as the element's atomic number. The atomic number is the number of protons in the nucleus of an atom, which also equals the number of electrons in a neutral atom.
What is equal to the number of protons?
An element's' atomic number, and in a neutral atom the number of its electrons.
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.
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.
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 are the numbers of protons and electrons in an atom?
The number of protons and electrons in a neutral atom are the same and given by the element's atomic number.
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 do you notice about the atomic number and the total number of electrons in an atom of that element?
The atomic number is equal to the number of protons in an atom, which also corresponds to the number of electrons in a neutral atom. This means that the atomic number gives you the total number of electrons in a neutral atom of that element.
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.
What can be said of the number of electrons of the one element can have?
A neutral atom of an element will have the same number of electrons as protons (atomic number). For example, the element magnesium has the atomic number 12, which means that a neutral magnesium atom will have 12 protons and 12 electrons.
What is equal to the number of electrons in a neutral atom?
In a neutral atom the number of electrons is equal to the number of protons. The opposite charge between protons and electrons is what allows for a neutral atom.
What does the atomic number tell you the number of in a neutral atom of an element?
The atomic number of an element is the number of protons in each atom of the element, whether neutral or not. If the atom is neutral, the number of electrons in the atom is the same as the number of protons.
The number of electrons in an atom of an element is the same as the element's?
The number of electrons in an atom of an element is the same as the element's atomic number. The atomic number is the number of protons in the nucleus of an atom, which also equals the number of electrons in a neutral atom.
