Is the valency of chlorine 7?
The chlorine element belongs to group 17 because it has 7 valence electron . Its valency is 1 .
What is the valency of chlorine with atomic number 17?
1
This shows chlorine has 7 valence electrons in its outermost shell. Accordingly, the valency of chlorine is 7-8 which is 1.
What is the number of electrons in the outermost shell of Cl?
7 electrons
Valence electrons are the number of electrons present in the outermost shell of an atom. The last shell of a chlorine atom has 7 electrons in it. Therefore, there are 7 valence electrons in an chlorine atom.
What is the number of electrons in the valence shell of chlorine Z 17?
The atomic number of chlorine is 17. Hence it has got 7 electrons in its outermost shell. There are 7 valence electrons in the chlorine atom.
What is the valence electron of chlorine?
[Ne] 3s² 3p⁵
Chlorine/Electron configuration
What is the valency of chlorine in cl2o 7?
Structure of Cl2O7 is given below. Each chlorine atoms are connected with four oxygen atoms. Hence the oxidation state of Cl is +7 and hence the valency of both Cl is 7 only.
How do you find the electron distribution for the element that has atomic number 17 and write its valency?
The atomic number of the element is 17, thus it has 17 electrons. Now, its valency will be = (8 – 7) = 1.
How many electrons does chlorine have in each shell?
List of elements with electrons per shell
Z | Element | No. of electrons/shell |
---|---|---|
17 | Chlorine | 2, 8, 7 |
18 | Argon | 2, 8, 8 |
19 | Potassium | 2, 8, 8, 1 |
20 | Calcium | 2, 8, 8, 2 |
What is valence electron of chlorine?
Which is the valence shell of chlorine?
seven electrons
Chlorine has an atomic number of 17. Here is the electrical configuration of chlorine. As a result, it possesses two electrons in its innermost shell, eight electrons in its second shell, and seven electrons in its outermost shell. As a result, the chlorine atom has seven valence electrons.
How many electrons are there in the outermost shell of chlorine?
The number of electrons in the outermost shell of chlorine is 7 . What is its valency and why? The number of electrons in the outermost shell of chlorine is 7 .
Why is the valency of chlorine 1?
The valency of chlorine is 1 because valency of an element is either equal to the number of valence electrons in its atom or equal to the number of electrons required to complete 8 electrons in the valence shell. Since chlorine is a non-metal so valency of nonmetal = 8 – the number of valence electrons in its atom which is 8−7 = 1.
Why do Group 7 elements have a valency of 1?
However, in the case of Group 7 elements alternatively called Halogen, despite having seven valence electrons, they have a valency of one as well because they need to gain/add just one electron to their valence/outermost shell to attain an octet configuration in the valence shell.
What is meant by valency of an atom?
Valency is the combining power of an atom i.e the number of valence electrons the atom will lose or gain The electrons in the outermost shell of an atom is the same as the valence electron number since valence electron number is the number of electrons in the outermost shell of an atom.
