The number of PROTONs and the number of ELECTRONs are always equal in a neutral atom.

Therefore an element with one PROTON will have one ELECTRON and that element will be called Hydrogen.

How many electrons are there in a neutral atom?

One electron. This balances out hydrogen's one proton.


How many electrons in one proton?

Electrons do not fit inside a proton or neutron. Electrons move around the nucleus where the protons and electrons are, and the mount of electrons depends on the atom. For a neutral atom the number of electrons = the number of protons. If that does not hold true the atom will receive a (+) or (-) charge. It will be a (+) if it is missing one electron and a (-) if it has an extra electron. To the guy who wrote that, the question was asking (in size) how many electrons could fit inside a proton relative to its size. The answer is about 1/1836 electrons could fit inside a proton.


How is the number of electrons is a neutral atom of a given element related to the atomic number of that element?

The atomic number tells you how many protons are in the element. The proton count is the same as the electron count as all elements have a charge of zero giving them the same. Simplified: the atomic number shows you how many electrons and protons are in the element. If it is a compound and it has a charge of +1 that means the element has lost one electron and has a positive charge. If it gained a electron it would be -1 as electrons are negatively charged.


How many valence electrons should an element to react with a element with 7 valence electrons?

one valence electron


Which element has the smallest number of proton in its atom?

The element with one proton per atom is hydrogen.

How many numbers of atoms does hydrogen have?

Hydrogen is an element, and the smallest form of an element is an atom. If you meant electrons, then 1.


How many electrons are in a neutral hydrogen atom?

One of course as Hydrogen is the first element on the periodic table and therefore has one proton and needs one electron to balance it.


Subatomic particle that defines the element?

The subatomic particle that defines the element is the proton. The number of protons in the nucleus of an atom determines the element's atomic number, which differentiates one element from another on the periodic table.


What element has one proton and zero neutrons?

Hydrogen ion is the only element that has no neutron and one proton. That is why it is basically a proton.


How many electrons doe carbon have?

Carbon has 6 protons, and it will have 6 electrons in a neutral atom, one for each proton. See link below.


What element is composed of one proton and one neutron?

Hydrogen [H] has one proton. Its atomic number is 1 which is the number of protons. Also, the number of protons will always equal the number of electrons unless the element has a charge.


What is the lightest element with only one proton?

The lightest element with only one proton is hydrogen.


How many electrons are there in a neutral atom?

One electron. This balances out hydrogen's one proton.


What ion has 8 protons and 10 electrons?

There is no atom or element that has one proton, one neutron and ten electrons. Duterium has one proton, one neutron and one electron (in a neutral atom). Tritium has one proton, two neutrons and one electron (in a neutral atom), but that is the closest. In any neutral atom the number of electrons will equal the number of protons in the nucleus of that atom. An atom with one proton in its nucleus and 10 electrons just isn't possible.


How many electrons are attracted by a proton?

There is no specific number of electrons that a proton can attract. For example, in a neutral atom; a proton attracts nearly one electron and there is a higher attraction in anions and lesser number in cations.


How many electrons does it take to equal to the mass of one proton?

electrons are a 2000th of the mass of a proton/neutron. Because of this very low mass, electrons dont affect the mass number of elements on the periodic table


How many protons does an atom of the first element listed on the periodic table have?

Hydrogen, being the first element, has one proton and one neutron in its nucleus.
