An atom will not normally form a chemical bond if it has how many valence electrons?

An atom will not normally form a chemical bond if it has 8 electrons already or in the case of hydrogen and helium, 2 electrons. A "full" valence shell has 8 electrons starting and period 2 on the Periodic Table. The elements with full valence levels are the elements on the far right family called the noble gases. The noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).

∙ 14y agoThe elements in Column 8 of the periodic table have their outer shell s and p orbitals full. They are called NOble gases,
That means 2 electrons in the s orbital and 6 in the p orbital

What is important about the valence electrons?
When an atom undergoes chemical change, only the outermost (valence electrons) are involved.
What are valence shells?
Electrons in the outermost orbitals of an atom. They determine the chemical reactivity of an atom and are the primary electrons that participate in chemical reactions.
What part of an atom is use in a chemical reaction?
Electrons - the valence electrons
What is an electron called in the outermost energy level?
They are called valence electrons, and they are responsible for an atom's chemical properties. During a chemical reaction, the valence electrons are the only part of an atom that participates.
Where in the atom are the electrons that are used to form bonds located?
The electrons that participate in chemical bonds are located in the "valence shell" or outer energy level of that atom. They are known as the valence electrons, and they are the only part of the atom that participates in a chemical reaction.

What re valence electrons?
Valence electrons are: In chemistry, those electrons found in orbits farthest from the nucleus of the atom. These electrons determine the way in which the atom will combine with other atoms, and thus determine its chemical properties.
Which subatomic determines the atoms chemical properties and why?
Valence shell electrons or valence electrons determine the chemical properties of an atom...

The electrons in an atom that are invloved in forming chemical bonds are called?
Valence electrons.

Are atom properties determined by the size of the valence electrons?
Valence electrons are very important for the chemical properties of chemical elements; but all electrons have identical sizes.
What part of the atom bonds in a chemical reaction?
the valence electrons
