Answer:
The nitrogen atom has 5 electrons in the outermost shell, so it can accept 3 electrons to fulfil the octet structure. Therefore the valency of nitrogen is 3.
Answer: carbon-containing compounds with covalent bonds
Explanation:
The term "organic compound" refers to the group of carbon-containing compounds such as glucose (C6H12O6), Propane (C3H8), ethyne (C2H2) etc, where the carbon atoms in them are covalently bounded to other atoms such as hydrogen, oxygen, phosphorus, nitrogen etc
Examples of organic compounds are ethanol (C2H5OH), ethylamine (C2H5NH2) etc.
Thus, organic compound are carbon-containing compounds with covalent bonds to other atoms.
Answer:
Heat energy.
Explanation:
The exited electron releases the absorbed energy as heat energy that provides energy to electrons to move from one orbit to another orbit. The electron avails kinetic energy which provides motion in the electron when the energy is absorbed by the electron while on the other hand, electron releases energy which brings the electron into its original orbit. So we can say that the electrons releases energy in the form of heat and come back to its original place.
The cell theory states that all cells come from other cells. When cells reproduce, they make copies of their DNA and make copies of their DNA and pass it on to the new cells.
