They determine many things. They can be used to predice hybridization, determine octet, be used to assign formal charges. The simplest answer would be for a intro to chem class, they determine the number of electrons in the atom's "outer ring"
Basically, the number of valence shell electrons determine the group to a particular element in the Periodic Table. When the group is determined, it enables to predict its chemical and physical properties.
They determen how reactive the element is with other elements
Valence electrons determine an atom's chemical properties including its reactivity.
They also determine the group that the particular element belongs to in the periodic table
They determine how great is the valence of a chemical element; they are the electrons involved in the formation of a chemical bond.
It represents the group it belongs to in the periodic table.
Valence electrons are the electrons from the last ring.
No, Selenium has 6 valence electrons while Bromine has 7. You can determine this because on the periodic table, Selenium is in Group VI while Bromine is in group VII.
5 valence electrons.
6 Valence Electrons
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
Fluorine is a halogen. All halogens have 7 valence electrons. There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals.
Valence electrons determine the reactivity of the element.
Valence Electrons
The valence is determined experimentally.
the number of valence electrons determine the reactivity of the atoms
They determine how great is the valence of a chemical element; they are the electrons involved in the formation of a chemical bond.
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.
The valence electrons of an element are mainly what determine an element's properties.
Chemical properties of an element determine by the number of electron
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
Valence shell electrons or valence electrons determine the chemical properties of an atom...
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.
Valence electrons are the electrons in the outermost shell. They are the electrons available for bonding and generally determine the number of bonds an atom can make
