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.
Does CL have 8 valence electrons?
Why? Referring to the octet rule, atoms attempt to get a noble gas electron configuration, which is eight valence electrons. Sodium has one valence electron, so giving it up would result in the same electron configuration as neon. Chlorine has seven valence electrons, so if it takes one it will have eight (an octet).
3 Answers. Chlorine has 7 valence electrons .
Does calcium have 2 valence electrons?
From the electronic configuration we know that the outermost shell of Ca is the fourth shell and the number of electrons in that shell is the valence electrons. Here there are two valence electrons in the outermost shell. So the number of valence electrons in Ca is 2.
The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds.
What is the element with 8 electrons?
So for the element of OXYGEN, you already know that the atomic number tells you the number of electrons. That means there are 8 electrons in an oxygen atom.
Why does chlorine have 7 valence electrons?
The atomic number of chlorine is 17. Hence it has 2 electrons in its inner-most shell, 8 electrons in its second shell and 7 electrons in outer-most shell respectively. Electrons in the outer shells that are not filled are called valence electrons. Hence it has got 7 electrons in its outermost shell.
Chlorine Ion (Cl⁻) have 18 electrons in their shell. So there are 8 valence electrons.
What are groups 3/12 called on the periodic table?
Group 3 To Group 12: Transition Metals
The elements from Group 3 to 12 are called Transition Metals.
What is CL valence charge?
Cl has 7 valence electrons. The valence electrons are 3s23p5. Add an electron and you have the same configuration as Ar, but with one less positive charge: Cl-. This is a stable Noble Gas Configuration.
How many electrons are there in Cl ion?
Again, it is more energy-efficient for chlorine to gain one electron than to lose seven. Therefore, it tends to gain an electron to create an ion with 17 protons, 17 neutrons, and 18 electrons, giving it a net negative (–1) charge. It is now referred to as a chloride ion.
If we look at the neutral chlorine atom, it has 17 electrons whereas the chloride ion has 18 electrons.
How many electrons does chlorine have in its outer shell?
The Group 7 elements – fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At) – have seven electrons in the outer shell.
