Atoms hold their electrons in valence shells, but each shell only holds so many electrons. If an atom's outer valence shell is full, it's inert (does not form bonds). If it's outer shell isn't full, then it will form bonds.

∙ 13y agoThe valence electrons, the electrons on the outside. For example lets take apart water: H2O. H stands for Hydrogen. O stands for Oxygen. Hydrogen has 1 valence electron, and Oxygen has 6 valence electrons. To combine 2 elements you need a combined total of 8 valence electrons. That is why elements combine, to fulfill their outer shell of valence electrons. So Oxygen has 6 valence electrons and needs 2 more. Hydrogen only has 1 valence electron, so 2 Hydrogen molecules are needed to fulfill Oxygens outer shell. That is why there is a 2 in H2O. The 2 stands for 2 Hydrogen molecules. 6+1+1=8

In the atom what type of particle determines the element that atoms represent?
proton you can change the number of neutrons and electrons and still have the same element
Which shell determines the chemical property of an element?
the outer shell - which 'wants' to be full.
What determines the reactive of an element?
The number of valence electrons determines reactivity. Valence electrons are the number of electrons in outermost shell.
The valence electrons largely determine the chemical properties of an element and are usually the only electron used in?
BONDING!
What determines their shape?
Amino acid sequence primarily determines a proteins shape, but secondary (alpha helix and beta sheet) and tertiary structures (Hydrogen bonding, other chemical bonding between structures) adds to it.
What particle of an element determines bonding?
Chemical bonding is related mainly to electrons.
Which subatomic particles are involveld in chemical bonding?
The valance electrons of an element are involved in chemical bonding.
What is bonding powder in the periodic table?
Bonding powder is not a chemical element.
Which element most resembles Silicon for chemical bonding ability?
carbon
What determines a chemical properties of an element?
The number and arrangement of electrons.
What characteristic of an element determines how its atoms can bonds with other?
The number of valence shell electrons will generally determine the bonding characteristics of the element in question.
Why is oxygen is different from any other element?
Special chemical reactions such as hydrogen bonding.

What determines an elements chemical properties?
Chemical properties of an element determine by the number of electron
