Answer:
six protons, six neutrons, and six electrons
Explanation:
Answer:
They are salts, ionic compounds
Explanation:
To know if they are covalent or ionic we need to check their difference in electronegativity. As an example mgcl2, mg has electronegativity of 1.2 and cl 3 so 3-1.2=1.8 which is bigger than 1.7 means it's ionic therefore they are salts
Iodine (I2) is an example of a non-electrolyte. This is a purple-black solid at room temperature. When heated, it turns to a gas (sublimation) producing a beautiful violet cloud. It dissolves readily in many organic solvents, producing violet solutions in most cases and yellow-brown solutions in alcohols. Iodine is not very soluble in water, but produces a slightly yellow solution. No ions are produced when iodine dissolves in any of these solvents.
Solar energy is so promising option as it is having very low operational cost but still it is not being used optimally throughout the world.
