The number of electrons will equal the number of protons in a neutral atom. And this will also equal the atomic number (the number of an element in the Periodic Table of Mendeleev).
What else can I help you with?
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.
How many total electrons are present if the atom is electrically neutral in chlorine?
A neutral chlorine atom has 17 electrons. You can know this because chlorine's atomic number is 17, which is the number of protons in the nuclei of its atoms, and a neutral atom has equal numbers of electrons and protons.
How do you find number of electrons in periodic table or how do you calculate the number of electrons?
A neutral atom has the same number of electrons as it does protons. The atomic numbers on the periodic table for each element are the number of protons. So, look up the element on the periodic table, note its atomic number, and you will then know the number of protons and electrons in a neutral atom of that element. For example, magnesium (Mg) has atomic number 12. So a neutral Mg atom would have 12 protons and 12 electrons.
How many electrons does an atom contain?
You need to know the atomic number to know how many electrons an atom has. You can find it next to the element's symbol on the periodic table. For example, lithium has an atomic number of 3. This tells us that a lithium atom has 3 protons. Now since atoms are neutral they must have the same number of protons and electrons, so lithium also has 3 electrons. Atoms can lose or gain electrons to become charged species called ions, in which the number of electrons will not equal the number of protons; however, in a neutral atom: atomic number = number of protons = number of electrons
How do you know how many electrons argon has?
Argon has 18 electrons because it possesses 18 protons in its nucleus, making it electrically neutral. The number of electrons in an atom is equal to the number of protons in the nucleus.
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.
How do you find the number of electrons in an atom if you know the number of protons and neutrons?
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.

How can atomic number be used to find the numbers of protons electrons and nuetron's?
The atomic number is the number of protons and therefore, assuming the atom is neutral, the number of electrons. You would need to additionally know the atomic mass to figure out the number of neutrons.
If an atom has 19 protons and 20 neutrons how much electrons does it have?
It depends. From the given information about the number of protons, we can be sure that we are talking about potassium. The number of neutrons in this case won't matter. If the question emphasizes "atom" then we can be sure that the particle is neutral. Then we know that for the particle to be neutral, it has to have the same number of electrons as protons. However, potassium will not stay neutral for long if given a chance. It will lose an electron when bonding with others, to eventually have 18.
Can you find an element if you only know the number of electrons in a neutral atom?
Yes. In a neutral atom, the +ve and -ve charges will be equal. Electrons are negatively charged, and protons have an equal and opposite positive charge. Therefore the proton number will equal the electron number. Elements are classified by their Atomic number, and this equals the proton number. So if you had a neutral atom with 6 elements, you know it has 6 protons in the nucleus and an atomic number of 6 - Carbon.
What do you need to know to find the numbers of protons in an atom?
the protons are the same number of electrons in a neutral atom and they aren't changeable but different signal
What can be determined if you know the atomic number of an electrically neutral atom?
The number of electrons can be determined if the overall charge and number of protons are known. If the charge of an atom is neutral, then how ever many protons it has it will also have that number of electrons.
Is the atomic number of an atom is 11 how many electrons does the atom have?
You cannot know for sure withoutmore information. An electrically neutral sodium atom (sodium has at. no. 11) will have the same number of electrons as protons; atomic number tells you the number of protons, so this atom has 11 protons and would have 11 electrons if electrically neutral, however, if the atom is charged, it could have more or fewer electrons. Sodium atoms in stars are highly ionized and may have just a few if any any electrons.
