State whether the firs sentence is true or false and also the second statement. 1. All normal atoms have exactly as many electrons surrounding the nucleus as there are protons within the nucleus. Thus, a normal atom has no charge. 2.The nucleus is composed of protons and neutrons. Neutrons are slightly more massive than protons and have no net charge.
Electron Affinity
When an element undergoes a chemical reaction, it either gains energy or loses energy. This gain or loss of energy is due to the phenomena that occur at atomic level. During reaction, atoms either gain electrons from other atoms or lose electrons to other atoms, and in that process, energy is produced.
P-Block Elements
Elements which are present on the right side of the periodic table are called p-block elements. In addition to the noble gases, they include the families of boron, mercury, nitrogen, oxygen and fluorine. These elements have diverse real-life implementations that we regularly experience around us.
Metals and Non-metals
The periodic table is composed of metals, semi-metals and nonmetal elements. The physical and chemical properties of metals and nonmetals differ from each other. The study of metals and nonmetals will help one to understand the appropriate application of the particular element.

3.Sharks and rays have their sixth sense called reception. Their sixth sense allows them to locate their prey hidden beneath the sand at the bottom of the ocean because of the electric field generated by the muscle contraction of the prey.
