Aneutral atom has 2 electrons in its K shell and 2 electromscin its L shell and 2 electrons in its M shell .Find the atomic number of the element.Write the symbol of the ion that will be obtained if the electrons in the M shell are removed from thevatom.
Answers
Answer:
12
Explanation:
There are 2 electrons in the M shell of the atom of this element. This means that the K and L shells of the atom of this element (which come before M shell) are completely filled with electrons. Now, K shell can accommodate 2 electrons, L shell can accommodate 8 electrons adn we have been given that M shell has 2 electrons. So, the electronic configuration of this element becomes 2,8,2. Thus, the number of electrons in its aton is 2+8+2=12. Since the number of electron in a neutral atom is equal to the number of protons, therefore, the atomic number of this element is 12.
Answer:
This type of element cannot be formed
Explanation:
In K shell 2 electrons are present
In L shell 8 electrons are present
In M shell 16 electrons are present
After all the L electrons fill we next go to M shell
