When dissolved in water, for example, they all produce germicidal solutions. Those elements with 1, 2, or 3 electrons in their outermost shell are the metals. Helium with its 2neonargonand krypton each with 8 have "filled" their outermost shells. They are the so-called inert or "noble" gases.
They have no chemistry at all. Under normal conditions they do not interact with other atoms. So, it is the number and arrangement of the electrons in the atoms of an element that establish the chemical behavior of that element. The number of electrons that an atom must acquire, or lose, or share to reach a stable configuration of 8 2 for hydrogen is called its valence.
Electron arrangement and chemical properties of Group 7 - Higher
Hydrogenlithium, sodium, and potassium atoms all have a single electron in their outermost shell. Fluorine, chlorine, bromine, and iodine atoms all have 7. The result of all of these interactions is a pair of atoms each with an outermost shell like that of one of the inert gases: The elements with 2 electrons in their outermost shell interact with chlorine and the other halogens to form, e.
Again, the result is a pair of atoms each with a stable octet of electrons in its outermost shell.
How many electrons does fluorine have in its outermost layer?
The elements with 3 electrons in their outermost shell will interact with chlorine in a ratio of 1: Carbon atoms, with their 4 electrons in the L shell interact with chlorine to form CCl 4. Nitrogenwith its 5 outermost electrons, interacts with hydrogen atoms in a ratio of 1: Oxygen and sulfurwith their 6 outermost electrons react with hydrogen to form water H 2 O and hydrogen sulfide H 2 S. Quick Answer An atom of fluorine has seven electrons in its outermost layer.

Full Answer Fluorine is so reactive that it reacts with all the other elements and can never be found in its elemental form in nature. Learn more about Chemistry Sources:. What are quantum numbers in chemistry? Explanation Explain in detail I want someone to double check my answer. Shivangi Mangotra and 2 others Share. Valence electrons are those electrons which are present in the outermost shell of an atom. In every stable Neutral atom the number of electrons are equal to the number of protons.
Therefore, the number of electrons in an atom of fluorine are 9.How to Find Valence Electrons! (and Total Electrons)
The electronic configuration of fluorine is: Let the contributor know! Write your answer here You can use fluorine's electron configuration to help you determine how many electrons are located in the outermost shell "F": This means that fluorine has a total of 7 valence electrons. The number of valence electrons for the main group elements can be determined by their group numbers as follows: See more How do you calculate molarity from titration data?
How do you find the volume between the sphere and How do you solve the right triangle ABC given After battle of Chickamauga, the troops on both What is the equation of the tangent line of f x Use power reduction identities to rewrite the Lewis Symbols are simplified Bohr diagrams which only display electrons in the outermost energy level.
Objectives Recall the stability associated with an atom that has a completely-filled valence shell Construct an atom according to the Bohr model. Key Terms Octet rule: A rule stating that atoms lose, gain, or share electrons in order to have a full valence shell of 8 electrons. Hydrogen is excluded because it can hold a maximum of 2 electrons in its valence shell.
The collective states of all electrons in an atom having the same principal quantum number visualized as an orbit in which the electrons move. Electron Shells Niels Bohr proposed an early model of the atom as a central nucleus containing protons and neutrons being orbited by electrons in shells.
Bohr Diagrams Bohr diagrams show electrons orbiting the nucleus of an atom somewhat like planets orbit around the sun. Lithium has three electrons: Its electronic configuration is K 2L 1 Fluorine has nine electrons: Its electronic configuration is K 2L 7.
Note that L can have 8 electrons. Aluminum has thirteen electrons: Its electronic configuration is K 2L 8M 3.
Note that the M shell can have 18 electrons. Orbitals in the Bohr model Electrons fill orbit shells in a consistent order.
