To answer that question, we don't care what the highest and lowest
levels of the wave are, or how far apart they are. We only need to be
able to identify the highest point on the wave, and keep track of how
often those pass by us.
You said it takes 4 seconds for a complete wave to pass by.
Through the sheer power of intellect, I'm able to take that information
and calculate that 1/4 of the wave passes by in 1 second.
There's your frequency . . . 1/4 per second, or 0.25 Hz.
Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Such a solution is called saturated. Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .
Answer:
The atom becomes a positively charged ion.
Explanation:
- The building blocks of an atom are protons, neutrons, and electrons.
- The protons and neutrons present in the core of the atom are called nucleus.
- The electrons are scattered in an ordered way around the nucleus.
- The protons are positively charged and the electrons are negatively charged particles. The neutrons do not possess any charges.
- Binding energy is supplied to the atom to remove an electron.
- It is possible to remove the electrons of the lighter elements.
- When an electron is removed from the hydrogen atom. It becomes positively charged ion or simply proton.
- When all of the electrons are removed from the helium atom, it becomes a positively charged α particle.
- It is practically very difficult to remove all of the electrons from the heavier elements.
- When all of the electrons are removed from an atom it becomes an unstable positively charged ion.
