non metals generally have more valence electrons and non metal have less
Metalloids have intermediate electronegativities between metals and non metals. As a result, they can donate, share, or accept electrons when forming bonds with other atoms. Metals only donate or share and non metals only accept or share.
Valance electrons are the electrons in the outer shell, they are all electrons no matter if it is a metal or non-metal atom.
They don't in any way that I'm aware of. If this is a homework question, read your textbook to see what cockamamie alleged difference the author came up with.
Sodium loses one electron when it reacts with a nonmetal.
Lithium is a metal, it reacts by losing an electron to form a positive ion. It is a member of Group 1 with sodium and potassium.
It is a nonmetal.
A nonmetal.
Helium is a nonmetal. Think about the helium balloon!
for example: metal-potassium nonmetal-fluorine
In a ionic bond, which is a bond between metals and nonmetals, the metal will loose the electron(s) while the nonmetal will gain the electron(s).
The metal gives its electron(s) to a nonmetal.
Sodium loses one electron when it reacts with a nonmetal.
Hydrogen has 1 electron. It can easily gain or lose electron to form metal or non metal
If the electrons are "stolen" from the metal by the nonmetal, an ionic bond is formed. If the electrons are shared between the metal and the nonmetal, a covalent bond is formed. If the electrons "resonate" between the metal and the nonmetal, a resonance bond is formed.
The metal tends to lose the electron because it has a higher electron affinity, and the nonmetal tends to gain the electron because it has a higher electronegativity. This has to do with the placement of the element on the periodic table. The further to the right you go, the more the element wants to gain electrons in an ionic compound.
Because the metal loses an electron (making it smaller) and the non metal gains that electron, making it larger.
When nonmetals bond with metals the nonmetals will take electrons from the metal to fill their electron shell and empty the shell of the metal. The electrical attraction of the (+) charged metal and the (-) charged nonmetal form an ionic bond between the two.Nonmetals share electrons in a covalent bond.
Lithium is a metal, it reacts by losing an electron to form a positive ion. It is a member of Group 1 with sodium and potassium.
NaCl Sodium chloride, common table salt. A metal nonmetal bond and the (metal) cation, Na +, has donated an electron to the (nonmetal) anion, Cl -.
Generally so because the electronegativity of the nonmetal far exceeds the metal's electronegativity and thus the nonmetal will " pull " the electron(s) into it's valance shell.
