Boron and aluminium are both found in group 3 of the modem periodic table. State what this tells you about the electronic configuration of both elements.
Explain what this tells you about the chemical properties of the two elements

Valence Electrons = 3

Explanation:

Not counting the transition metals, Boron and Aluminum are in group 3, but are actually in group 13. These elements usually have 3 valence electrons. Every element wants a full octet, or a full valence shell of eight electrons. It can do this by reacting with other elements through some bonds. Elements like these are not very reactive, especially in comparison to the alkali metals.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
