Answer: yes
Explanation: Radioactive (or nuclear) waste is a byproduct from nuclear reactors, fuel processing plants, hospitals and research facilities. Radioactive waste is also generated while decommissioning and dismantling nuclear reactors and other nuclear facilities. There are two broad classifications: high-level or low-level waste.
Explanation:
Ionic bonds are bonds formed as a result of the electrostatic attraction between two species.
- This bond type is an interatomic bond.
- It forms when two specie with a large electronegative difference between them combines.
- This is usually a metal and a non-metal.
- The metal loses its valence electrons and becomes positively charged.
- The non-metal gains the electron and becomes negatively charged.
- An electrostatic attraction between the two specie leads to the formation of an ionic bond.
- They are solids with a high melting point.
- They are soluble in polar solvents.

1) A. the have different protons.
The number of protons is the atomic number and this is how the products are ordered in the periodic table. Every element has different atomic number.
2) A. 8 p, 8 e and 8 n
The atomic number of O is 8, which means it has 8 protons. The number of protons must equal the number of electrons.
3) C. atoms bond with one another in a molecule.
That is what a molecule is: a group ot atoms bonded.
4) D. the bond results from the attractive forces of two opposite charges.
Ionic bonds are formed between ions, a positive ion (cation) and a negative ion (anion).
5) A. the physical and chemical properties of HCl are different from those of H2 and Cl2
You can check physical properties (density for example) and chemical properties (how they react with other elements) in some tables o textbooks.
Explanation:
A matchstick has a lot of chemical energy stored in it. When the match is struck, it burns and the chemical energy in it produces heat energy and light energy.

The process of chemical weathering by oxygen and water on iron is known as rusting........rust is a loose reddish brown layer of hydrated ferric oxide(Fe2O3.H2O)
