Na mg al si and p are the first 5 elements of 3rd period which among these elements is more electropositive why
Answers
Electropositive elements : sodium, magnesium.
The definition of electropositivity is the tendency of an atom to lose electrons from its outermost shell and become positively charged ion (cation)
Hope it helps................
Sodium is most electropositive
Explanation:
Electropositivity is defined as the property of an element to lose a electron with ease to acquire a positive charge.
In a period, as we move across from sodium to phosphorous , with atomic numbers ranging from 11 to 15, the ionization energy increases as we move across a period as the size decreases and thus the valence shell moves nearer to the nucleus and thus is difficult to remove the electron and thus electropositivity decreases.
Thus sodium has highest electropositivity.
