Molecules in solids are packed a lot closer together than molecules in liquids and gases, so there is far less space between solid particles. Because of this, solid particles cannot move around quickly and freely like liquids and gases, instead they only vibrate so are fairly 'locked' into the same place, so solids have fixed volume and space.
Protons and neutrons are in the center
electrons orbit around the center/nucleus
Answer:
The planets follow these orbit paths as they travel around the Sun. The Sun’s gravity
makes the planets move in this way. It pulls on the planets, keeping them in motion in their orbit.
Modeling is a way to see ideas or have a particular idea or
concept.
Models do have some lines .
Often a model is made with certain things.
A model of the solar system may contain all of the planets and the Sun, but it may not include the planets’
individual moons or every planit and rock in the solar system.
Explanation: if you think about it and and look at pics it is easy

To calculate the pH of a solution that has a [H3O+] of 7.22x10^-7. You would do the following
pH=-log[H3O+]
pH=-log[7.22x10^-7]
pH=?
