they determine weather or not it bonds. the valence are the outer shell, the noble gases don't react because the shell is full. but molecules want to have 8 total so they can share or trade, but one can give all its valence to another atom which fills that one and the other one's lower shell is full. look in a chem textbook, talk to your teacher or look online if you want a more in-depth explanation
Electrons in the outermost shell are valence electrons!
3 electrons !
There are 3 valence electrons in an atom of aluminium.
Indium has 3 valence electrons.
8 valence electrons- 1s22s2p63s2p6
Electrons in the outermost shell are valence electrons!
Valence electrons
the electrons in the outermost shell of an atom are considered to be the valence electrons.
3 electrons !
The importance of valence electrons is that atoms in the same group ("groups" in the periodic table are the vertical columns- for example, nickel and platinum are in the tenth column; therefore, in the same group). Atoms of elements in the same group have the same number of valence electrons, so they have similar properties. Hope that helped with your homework! ;D
The valence electrons of an atom determine how the element forms chemical bonds with other elements to form chemical compounds.
There are 3 valence electrons in an atom of aluminium.
Indium has 3 valence electrons.
Yes, krypton has eight valence electrons.
The beryllium atom has 4 electrons and the valence is 2.
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
Boron has 3 valence electrons, gold has 1 valence electron, krypton has 8 valence electrons, and calcium has 2 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom.
