What are 3 differences between ionic and covalent bonds? An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between identical atoms. Ionic bonds form between a metal and a nonmetal. Covalent […]

What happens when you mix sodium and chlorine?
What happens when you mix sodium and chlorine? If sodium metal and chlorine gas mix under the right conditions, they will form salt. The sodium loses an electron, and the chlorine gains that electron. This reaction is highly favorable because of the electrostatic attraction between the particles. In the process, a great amount of light […]

What is the application of sound?
What is the application of sound? While we cannot hear ultrasonic waves, we apply them in various technologies such as sonar systems, sonograms, surgical tools, and cleaning sytems. Some animals also use ultrasonic waves in a specialized technique called echolocation that alows them to pinpoint objects and other animals, even in the dark. What are […]
Where are water masses formed?
Where are water masses formed? Water masses are formed as the result of climatic effects in specific regions. Antarctic bottom water is an important water mass that forms on the Antarctic continental shelf as a cold, dense residual brine during the formation of sea ice. Which water mass is the saltiest in the world? That […]
How can we determine the size of the Earth?
How can we determine the size of the Earth? It was generally agreed upon that measuring the size of Earth could be done by measuring the altitude of a star from two cities situated on the same meridian. Then, a difference expressed in degrees would be found. How is the Earth’s curvature measured? How could […]
