Question

An element has an atomic number 12 and mass number 26. Draw a diagram showing the
distribution of electrons in the orbits and the nuclear composition of the neutral atom. If this
element X combines with another element Y whose electronic configuration is 2,8,7, what will be the formula of the compound thus formed?

Answer 1

Answer:

(i) An element X has an atomic number = 12 and mass number = 26. Draw a diagram showing the distribution of electrons in the orbits and the nuclear composition of the neutral atom of the element. What is the valency of the element and why? (ii) If this element X combines with another element Ywhose electronic configuration is 2, 8, 7. What will be the formula of the compound thus formed? State how did you arrive at this formula.
