None. Protons are a subatomic particle, as are electrons and neutrons. Three different kinds - at least until you start talking about quarks, which are more fundamental than protons and neutrons.
A valence electron is simply one in the outermost quantum level, making it possible to be shared between atoms - this is called a covalent bond.
What else can I help you with?
What element has 1 valence electron and 19 protons?
Potassium
How many valence electron does methane has?
4 valence electrons are present in methane
Are valence electrons located in the electron cloud?
The outermost shell of an electron is called the valence shell. This shell may or may not have electrons.The valence shell is a part of the electron cloud.So your answer isYes, the valence electrons are located in the electron cloud.
How many valence electron can any atom have?
The number of valence electrons depends on the atom and can vary from 1 to 8.
How many protons and eletrons does carbon have?
count the number of protons which will be equal to number of electron.
How many protons electrons and valence electrons does na have?
Sodium's atomic number is 11. To be neutral then, it must have 11 protons and 11 electrons. Since sodium is in group 1, it has 1 valence electron.
Which element has 19 protons and 1 valence electron?
Potassium has 19 total electrons and one electron in its 4th energy level.
What element has 1 valence electron and 19 protons?
Potassium
How many protons neutrons and electrons does Mo have?
The neutral atom of molybdenum has 42 electrons.
What is the difference between a valence electron and a shielding electron?
Valence electrons are electrons on the outermost shell/orbitals. Sheilding electrons are inner electrons that block valence electrons from protons causing less attraction.
How many valence electron does alkali metals have?
Alkali metals have one valence electron.
Calculate Z eff for a valence electron in an oxygen atom?
The effective nuclear charge (Z_eff) experienced by a valence electron in an oxygen atom can be calculated by considering the number of protons in the nucleus minus the number of core electrons shielding the valence electron. For oxygen with 8 protons and 2 core electrons in the 1s orbital, the Z_eff for a valence electron in the 2s or 2p orbital would be approximately 6 (Z_eff = 8 - 2).
How many valence electrons does gold have?
The number of electrons in a neutral atom of any element is the same as the number of protons in the nucleus of the atom. The number of protons in an element is the same as the atomic number for that element. In the case of Gold (Au) the atomic number is 79.
Hydrogen has how many valence electrons?
One. A hydrogen atom contains only one electron, and it is a valence electron.
How many valence electrons are in alkali metals?
one valence electrons
How many valence electron does an excited potassium electron have?
one electron
What is the unknown substance if it is determined that is has 55 protons 57 neutrons and 1 valence electron?
It is a Cesium isotope, with the atomic mass of 112.It could also be an ion depending on how many total electrons it has.
