Atom of an element react with other atoms, to achieve …………………… in their outer most shell.

What is valency of an atom? Explain how an atom can achieve an octet in their outermost shell and also explain how an atom can be chemically stable.

The most common oxidation state of an element is -2. the number of electrons present in its outer most shell is-

The most common oxidation state of an element is -2. The number of electrons present in its outer most shell is:

The atomic number of an element is 35 and mass number is 81.The number of electrons in the outer most shell is

P: Kernel is the nucleus and all other electrons in the atom except the outer most shell electrons. Q Valency is the outermost shell.

The atomic number of an element is 86 . The number of electrons present in the outer most orbit and the number of orbits are
