7 electrons
Look at how the element Cl is located in the 17th column of the Periodic Table of elements. We simply take the second digit of that number (7) to find the numbers of electrons in the valence shell.
Notes:
- A full valence shell can only have up to 8 electrons.
- Answer is correct, but reasoning may be wrong.

What is an element with 7 valence electrons and 4 energy levels?
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.
Which elements have the same energy levels of aluminum?
Aluminum has it's valence electrons in the 3rd energy level. Others that also have valence electrons in n=3 would be Na, Mg, Si, P, S, and Cl. Argon also has a filled 3rd level.
How many valence electrons consult of the periodic table chorine?
Chlorine (Cl) has 7 valence electrons, as it is in Group 17 or 7A of the periodic table. This means it has 7 electrons in its outermost energy level.
What energy level are the valence electrons located in lithium?
2nd energy level, the electron arrangement is 2,1 at ground state
What is the number of the prinicpal energy level in which valence electrons are found?
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
Valence electron are found in what energy level?
Valence electrons are found in the outermost energy level of an atom, also known as the highest principal energy level. These are the electrons involved in chemical bonding and determining the reactivity of an element.
What is the word for the definition electrons in the outermost energy level of an atom?
valence electrons are the electrons in the outermost energy level
What is the electronic stricture for chlorine?
Cl has the electron configuration1s2 2s2 2p6 3s2 3p5the 1s2 2s2 2p6 electrons are the core electronsthe 3s2 3p5 electrons are the valence electronsthe electron structure of Cl would show the valence electrons as 3 lone pairs and 1 single electron .... sorry can't show diagram
What is a valence or shell?
The outermost energy level of an atom is referred to as the valence shell.
What are electron in the outer energy level called?
Valence electrons.
What is the outer most energy level of an atom?
This is the valence shell and is involved in bonding e.g. the sharing or loss of electrons to form a molecule or giant structure. Inner shells do not take part in bonding though their shielding effect and repulsion does affect the loss and gain of electrons from this shell.
How do you figure out valence shell and valence electrons?
To determine the valence shell, look at the outermost energy level of an atom (the highest value for "n" in the electron configuration). The valence electrons are the electrons in the outermost energy level of an atom, which are involved in bonding and chemical reactions. Count the number of electrons in the outermost energy level to find the valence electrons.
