Answer: True
Explanation: Frequency by definition is the number of waves that pass a fixed point given a certain amount of time. The shorter the wavelength, the higher the frequency.
Answer:
Copper is a metal made up of copper atoms closely packed together. As a result, the electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons because they help copper be a good conductor of heat and electricity.
Explanation:
Electron - In an atom, the central part which is composed of neutrons and protons including quarks is called the nucleus. Whereas the electron is the particle with negative elementary electric charge can be found inside the atom surrounding the nucleus.
If they didn't, they wouldn't be able to communicate their findings effectively. An international language is especially important for elements because many elements have similar properties (e.g. some of the transition metals).
