What is the difference between a stable and unstable electronic configuration?
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
What is the electronic configuration for the element phosphorus?
Shell Type EC: 2,8,5Quantum Shell EC: 1s22s22p63s23p3
What is the valence shell of the element boron?
Electronic configuration of B is 1s2 2s2 2p1 So valence shell is 2p
What orbitals electrons always add to the valence shell?
Because the inner shell already has completely filled electronic configuration.
How many electrons are in the out ter shell of cesium?
One. Cesium has the electronic configuration of [Xe] 6s1
How can the periodic table help scientist infer the properties of these elements?
Periodic table was constructed by using electronic configuration . Elements have same outer shell electronic configuration were in same group . So they have similar chemical properties . If an unknown element will register in future , its properties are predicted with the help of its outer shell configuration.

How many electrons are in the first orbital shell in the element neon?
There are two electrons in the first shell of neon. Its complete electronic configuration is 2,8
What is a chemical bond formed by?
Chemical bonds are formed by sharing of electrons between two atoms. Atoms tend to achieve electronic configuration of their respective inert gases i.e. in the outer shell they need to have 8 electrons. e.g. Sodium has 1 electron in the outer shell by donating it it is left with electronic configuration of 2, 8. and Chlorine which has 7 electrons in its outer shell receives 1 electron and gets electronic configuration 2,8,8. Between Sodium and Chlorine ionic bond is formed and NaCl is produced. Chemical bonds are formed by sharing of electrons between two atoms.
