Dipole Moment of Molecules

A molecule’s dipole moment is a measure of its polarity, representing the separation of positive and negative charges.

Alkaline Earth Metal

Alkaline earth metals are the six elements in Group 2 of the periodic table: Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra). They are shiny, silvery-white, moderately reactive metals known for forming basic (alkaline) solutions in water and having two valence electrons, which they readily lose to form +2 ions, making them important in ionic compounds.

Valency of Elements

Valency is the combining capacity of an atom, referring to the number of electrons it can gain, lose, or share to form chemical bonds. It is determined by the number of electrons in an atom’s outermost shell (valence electrons) and its ability to achieve a stable electron configuration, often like that of a noble gas.
