1.	It is the _______ of an element which decides the group and the period of an element in which it is to be placed.1️⃣ Atomic mass2️⃣ Atomic number3️⃣ Electronic configuration4️⃣ Valence electron
Answer» Answer: VALENCE electrons Step-by-step EXPLANATION: The position of element depends UPON its ELECTRONIC configuration. The number of SHELLS is equal to the period number. The valence electrons decides the group number in which it will be, elements with 1 valence electrons belong to group 1.
