Question

Explain how you can predict the products of a simple chemical reaction based on the outermost electron state of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties. *

Answer 1

Answer:

Atom's chemical properties are determined by the number of electrons in its outermost shells.

Based on the number of electrons in the shells, it decides the reactivity of atoms.                                                                                                                                    

Atoms with same number of electrons in the outer shells have similar chemical properties.

If atoms have 1,2 or 3 valence electrons they react by giving out those electrons to become stable. If atoms have 6 or 7 electrons in the outer shell they react by taking in electrons to complete its outer shell.
