Boyle's law states volume and pressure have an inverse relationship.
- Hope that helped! Let me know if you need further explanation.
1) Atomic radius: It increases from left to right in a period
2) Ionic radius: It increases from left to right in a period
3) First ionization energy: It increases from left to right in a period
4) Melting point: Generally decreases from left to right in a period
Because their atoms have the same number of electrons in the highest occupied energy level
What context are you asking it in?
The answer could be the electromagnetic interaction if you're talking about the 4 fundamental interactions, or ionic interaction, or electrostatic interaction.
