How does the electron configuration affect the reactivity?

Answer 1

Valency determines the chemical properties of an atom by indicating how many unpaired valence electrons an atom has, allowing a chemist to determine how many and possibly what type of bonds the atom may form with other elements.

For example, most elements with a "full valence shell" of 8 valence electrons (following the Octet Rule) will not react in solution because they cannot form bonds with other elements.

Answer 2

Valence electrons are very important because it gives us the oppurtunity to distinguify certain features special for atoms that have the same amount of valence electrons. For example, group 17 (the halogenes) have seven valence electrons each. This make them quite reactive, seeing as how they strive towards fulfilling the octett rule (that is to have 8 electrons in the outer shell). On the other side of the Periodic Table, we have the alkali- and the alkali earth elements, which have one, respectively two extra electrons in their outermost shell. This enables these to be quite reactive as well, seeing as how easy it is, especially for the alkali metals, to donate one electron to fulfill the octett rule. Through the use of the periodic table and these type of observations, we are able to predict that, for example Francium would be an extremely reactive chemical, if one were to gain hold of enough material of it, simply because we know that other alkali metals are reactive.

Summaring, since the atoms in each group contains the same number of valence electrons, we can predict that these atoms will have similar properties throughout the group.

Answer 3

the valence electrons are responsible for an element's reactivity,

it also determines where an element is in the periodic table.

Answer 4

What determines the chemical behavior of an atom / element?

Answer 5

The amount of electrons on the outer shell of the atom effect how chemically reactive it would be.

Answer 6

The chemical behavior of an atom is largely dictated by how it reacts to other atoms. This is controlled by the number of valence electrons an atom has.

Answer 7

The number of valence electrons influences an elements reactivity. Generally the more filled the outer shell is, the less reactive the element is.

Answer 8

Occasionally i like to fart on cold windows and lick off the condensation.

Answer 9

Valence electrons

Answer 10

Yes, it is correct.
