How many electrons are in a neutral atom atomic number 6?

In a neutral atom, the number of electrons is always the same as the atomic number.


Neutral atoms of argon atomic number 18 have the same number of electrons as each of the following items except?

Neutral atoms of argon (atomic number 18) have 18 electrons. Consequently, they do not have the same number of electrons as hydrogen (1 electron), helium (2 electrons), or lithium (3 electrons).


Is the number of electrons the atomic number?

Yes, the number of electrons in a neutral atom is equal to the atomic number.


What is the relationship between the atomic number and the electrons in neutral atom?

In a neutral atom the number of protons is equal to the number of electrons. And by definition the atomic number of an atom is equal to the number of protons in it. So the atomic number of a neutral atom is equal to the number of protons or the number of electrons in the atom.


What indicates the number of an electron in a neutral atom?

The number of an electron in a neutral atom is indicated by the atomic number, which is equal to the number of protons in the nucleus of the atom. In a neutral atom, the number of electrons is the same as the number of protons.


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 atomic mass number of protons or number of electrons if a neutral atom?

Neither, except for the anomalous hydrogen-1 isotope. The atomic mass number of an atom is the sum of the numbers of protons and neutrons in the atom. If the questioner meant "atomic number" instead of "atomic mass number", the atomic number is fundamentally the number of protons, but if the atoms is neutral, the numbers of protons and electrons are the same.


What is the atomic number of a neutral atom having 6 electrons and 5 neutrons?

Atomic number is 6. The isotope is 6C11 Atomic number = number of protons = number of electrons (for a neutral atom)


What is the formula used to calculate the number of electrons when only the atomic number is given?

The number of electrons is simply the same as the atomic number, assuming the compound or element is neutral (not positive or negative). To find the number of neutrons, take the atomic mass and subtract atomic number. The number of electrons is simply the same as the atomic number, assuming the compound or element is neutral (not positive or negative). To find the number of neutrons, take the atomic mass and subtract atomic number.


Does the number of electrons in an atom give its atomic number?

The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.


What are electrons on a periodic table?

Periodic table lists the elements in the increasing order of atomic number. Atomic number = Number of protons = Number of electrons


How is an atom's atomic number related to it's number of electrons?

For neutral atoms the atomic number is equal to the number of electrons.
