The answer is noble gas

Answer:

IT SHOULD BE AN ALKALI METAL

Explanation:

THIS IS BECAUSE ALKALI METALS HAVE 1 VALANCE ELECTRONS AND THEY ARE IN GROUP 1

ALKALINE EARTH METALS ARE IN GROUP 2 AND HAVE 2 VALANCE ELECTRONS

TRANSITION METALS ARE BETWEEN GROUP 3 TO 12

NOBLE GASES HAVE NO VALANCE ELECTRONS
