An element with atomic number___ will form a basic oxide.
(a) 7 (2,5)
(b) 17 (2,8,7)
(c) 14 (2,8,4)
(d) 11 (2,8,1)
Answer:
(d) 11 (2,8,1)
Basic oxides are formed by the reaction of metals with oxygen. Metals are the elements having 1-3 electrons in their outermost shell. So, the element with atomic number 11, having 1 electron in its outermost shell will form a basic oxide.
