What is the outer-most shell of an atom called?
valence shell
Number of valence electrons for k?
The valence shell is the outermost electron shell containing electrons.
How many valence electrons does silica have?
4
How many electrons will be in the valence shell of an aluminum atom?
there are 3 valence electrons in the atom of aluminum
In what ways are the electron configurations of H Li Na K Rb and Cs similar?
They all have 1 electron in their outermost shell
How can the atom K obtain eight valence electrons?
Need help understanding how the K atom could obtain eight outer shell electrons?
How many electrons does a boron atom have in its outer shell?
Boron has 2 orbitals
Does Argon have a bigger atomic radius then Neon?
I would say no. The potassium atom has 1 valence electron which is in the 4th valence shell. To form the potassium ion, it gives away this electron - thus becoming K+. Now, it has no electrons in the 4th valence shell - they are all in the 3rd valence shell. Argon also has all of its electrons in the 3rd valence shell. Also, K+ now has the same number of electrons as Argon. The reason why, at least I would say, argon has a larger radius than K+ is that even though they are in the same valence shell and have the same number of electrons, argon has one less proton than K+. This means that argon's nucleus does not pull in its electrons with quite as much force as K+. Therefore, the electrons (on average) are not as close to the nucleus as with K+. At least, this is how I would reason this out.
Why k shell has low energy than valence shell?
AnswerK-shell electrons generally have much larger binding energies than valence shell electrons. Can you give me a specific example or some more information to clarify your question? is energy level depend on electrons, i means is the shell having more electrons have more energy?
What is common to the electronic configuration of Li and K?
The outer shell contains 1 electron, ns1 Li [He] 2s1 K [Ar]4s1
How many valence electron are in an atom k-42 in the ground state?
Just one valence electron. The electron configuration for K-42 is 2-8-8-1, meaning that there is one electron in the outermost "shell" of the atom.
What electrons are in an electron dot diagram?
they are the electrons in the outer shell of the atom(valence electrons)
