Least reactive element in group 15
Nettet(i) Reactivity with hydrogen: Group 15 elements form hydrides of the type E H 3 where E is group 15 element. On moving down the group, the stability of hydrides decreases. … NettetIn general, atoms are most stable, least reactive, when their outermost electron shell is full. Most of the elements important in biology need eight electrons in their outermost …

Nettet2.1. 1.9. Some of the trends in the modern periodic table with respect to group 15 elements of the p-Block elements are discussed below. 1. Electronic Configuration. The valence shell electronic configuration plays a major role in how an element behaves. The valence electron shell configuration of group 15 elements is ns 2 np 3. NettetAnswer: (i) Number of valence electrons in X and Z will be 7 because the number of electrons in the outermost shell in the elements in same group is same. (ii) In Na, Al and P number of occupied shells are three. The reason for this is that elements with same number of occupied shells are placed in same period.
NettetProcedure 1: All the reactants were liquids that evaporated. Procedure 2: A gas was formed as one product, and it escaped into the air. Procedure 1: One of the reactants was converted to thermal energy. Procedure 2: All the products were liquids. Procedure 1: The reactants were liquids with different densities.
