WAEC SSCE - Chemistry - 2002 (Objective)

Question 1 Report

The atom of an element X is represented as \(^y_z X\). The basic chemical properties of X depend on the value of

Y - Z

Z - Y

Answer Details

In the symbol of an element, the number of protons (Z) in its nucleus is called its atomic number. The atomic number determines the element's identity and its basic chemical properties. Elements with the same atomic number have the same number of protons, so they have the same electronic configuration, meaning they have similar chemical behavior. Therefore, the value of Z in the symbol \(^y_z X\) determines the element's basic chemical properties.
