Answer:
Non metals join to form covalent bond.
Explanation:
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.
Both atoms bonded through covalent bond.
In Cl₂ both chlorine atoms are bonded through the covalent bond.
Answer:
In the picture, it's shown that the energy from the sun and carbon dioxide is absorbed by plants through the leaf and is used for cooking food in plants. It is also shown that nutrients and water needed for the plant is absorbed through the roots of the plant. And it's also shown that cooking results in the formation of Glucose and Oxygen in which oxygen is released into the atmospehere and the glucose is stored in the plant for its own needs.
