Valence electrons are the electrons in the outermost shell of an atom. These electrons are important in bonding and magnetism. For example, carbon has 4 valence electrons. It can make 4 covalent bonds to fulfill the octet rule. Also, if an atom has unpaired electrons, it is called paramagnetic and if an external magnetic field is applied, it will be attracted. If all of the electrons are paired, it is diamagnetic and will be repelled by an external magnetic field.

Why is valence electron important in chemical bonding?
Valence electron is important in chemical bonding because it has chemical energy so you can eat and it also is because it is.
What is special about the outer electron orbits of helium?
Helium has only two valence electrons. All other noble gases have 8 valence electrons.
What is the number of valance electrons in atoms from alkali metals?
they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.
How many numbers of valence electrons in potassium?
There is only one valance electron in potassium.
How many valence electron does an excited potassium electron have?
one electron
What is the valence electron of argon?
Valence electrons are the outer layer of electrons, the part that reacts. Argon is a noble gas, so it has a full valence electron level. It has eight valence electrons.
How many valance electrons does hydrogen have?
Hydrogen has only one electron. Just the one. And it is a valence electron.
An electron in the outermost energy level of an atom is a?
The outermost electrons are called VALENCE electrons.
What is the valence electron configuration for the phosphorus atom?
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
Why is valence electron important in chemical bonding?
Valence electron is important in chemical bonding because it has chemical energy so you can eat and it also is because it is.
How many electrons are in the valence shell of francium?
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
What is special about the outer electron orbits of helium?
Helium has only two valence electrons. All other noble gases have 8 valence electrons.
What are the electrons in the outer shell of an atom called?
valence electrons
How many valence electrons does Na have?
One. Sodium is found in Group 1, which is characterized by having one valence electron, so by extension, potassium, rubidium, cesium, and francium also have one valence electron.
What is the number of valance electrons in atoms from alkali metals?
they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.
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.
The elements in group 7A have one valence electron true or false?
A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.
