The element chlorine has seven electrons in its valence shell.
It's outer valence electron shell(s).
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
It depends on the number of electrons in the outer valence shell in the atom
The dots are the valence electrons in the outermost shell of an element. The number of valence electrons are the group number of the element (H=1, O=6, C=4 etc.)
Valence.
A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.
Group 18 (the noble gases) are completely made of special gases. They have a complete valence electron shell is the mainest reason they are important. They are actually not able to combine with any other element because they satisfy the octet rule (having a complete valence electron shell).
The element chlorine has seven electrons in its valence shell.
The outermost shell of an electron is called the valence shell. This shell may or may not have electrons.The valence shell is a part of the electron cloud.So your answer isYes, the valence electrons are located in the electron cloud.
On the last electron shell; iodine is a monovalent element.
It's outer valence electron shell(s).
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Under normal conditions Helium will not react with anything because it has a complete outer electron shell.
