Question

chapter 2: essential chemistry for biology

1. complete the diagram illustrating ionic bonds. atom x gives 1 electron to each atom y. what are the ions that form as a result? put the charges under each atom.

Explanation:

Step1: Understand electron - transfer in ionic bond

When an atom donates an electron, it becomes a positively - charged ion. When an atom accepts an electron, it becomes a negatively - charged ion.

Step2: Determine the charge of Atom X

Atom X gives 1 electron to each of the two atom Ys. So, Atom X loses 2 electrons. The charge of Atom X will be $X^{2 + }$.

Step3: Determine the charge of Atom Y

Each Atom Y accepts 1 electron. So, the charge of each Atom Y will be $Y^{-}$.

Answer:

Under Atom Y: $Y^{-}$
Under Atom X: $X^{2 + }$
Under Atom Y: $Y^{-}$
