Neon has 8 valence electrons, which gives it a full shell so it cannot interact with outher elements. This is why it is called a noble gas. Pdf expert download for mac. A valence electron is an outer shell electron and may participate in the formation of a chemical bond. Ok but how many valence electrons does an atom of Neon have? In the case of Neon the valence electrons is 0. Now let's check the facts about Neon. Neon Overview Neon Valence Electrons 0 Atomic Number 10 Learn more about the atomic number. The element that satisfies the given option should be chlorine with 7 valence electrons and 17 protons / 17 electrons (in total).Note: Oxygen has 6 valence electrons, neon has 8 valence electrons.

Learning Objectives

• Define valence electron.
• Be able to indicate valence electrons when given the electron configuration for an atom.

What makes a particular element very reactive and another element non-reactive?

A chemical reaction involves either electron removal, electron addition, or electron sharing. The path a specific element will take depends on where the electrons are in the atom and how many there are.

Electron Configurations of Second-Period Elements

Element Name	Symbol	Atomic Number	Electron Configuration
Lithium	Li	3	1s22s1
Beryllium	Be	4	1s22s2
Boron	B	5	1s22s22p1
Carbon	C	6	1s22s22p2
Nitrogen	N	7	1s22s22p3
Oxygen	O	8	1s22s22p4
Fluorine	F	9	1s22s22p5
Neon	Ne	10	1s22s22p6

In the study of chemical reactivity, we will find that the electrons in the outermost principal energy level are very important and so they are given a special name. Valence electrons are the electrons in the highest occupied principal energy level of an atom. In the second period elements listed above, the two electrons in the 1 s sublevel are called inner-shell electrons and are not involved directly in the element’s reactivity or in the formation of compounds. Lithium has a single electron in the second principal energy level and so we say that lithium has one valence electron. Beryllium has two valence electrons. How many valence electrons does boron have? You must recognize that the second principal energy level consists of both the 2 s and the 2 p sublevels and so the answer is three. In fact, the number of valence electrons goes up by one for each step across a period until the last element is reached. Neon, with its configuration ending in s²p⁶, has eight valence electrons.

Summary

• Valence electrons are the outer-shell electrons of an atom.
