This atom is on the almost extreme right of the 2nd period of the periodic table (except for the stable element on the extreme right). This means it has the highest mass number of the unstable elements of the period. It thus attracts its electron clouds more strongly that the elements to the left of the period . This means it can gain an atom easily ( this is what is called electronegativity – tendency to attract an electron) than is can lose an electron. In addition, it only needs to acquire one electron to achieve a stable electron configuration (8) in its valence shell.

Due to these, it is hard for the atoms to lose an electron which is why it has a high ionization energy- the energy required to lose an electron.

as the bright sun shines upon the water the water slowly disappears the same sunlight gives energy to the surrounding plants to

Well when the sun makes water dissaper thats usually evaporation.

The chemical changes is when the plants absorb the energy from the sunlight and convert water and carbon dioxide into sugar and oxygen gas. Physically nothing has changed. The plant still looks the sam changes occur internally these internal changes are chemical in nature.
