The +17 is referring to the number of protons within the atom. The minus signs with circles around them represent electrons orbiting the nucleus.
Answer:
the process by which substances in their gaseous state are converted to the liquid state.
Explanation:
When pressure on a gas is increased, its molecules closer together, and its temperature is reduced, which removes enough energy to make it change from the gaseous to the liquid state.
Answer:
It is hard to spilt a nucleus.
possibly the biggest concern among nuclear energy advocates is the environmental impact of uranium as a fuel source. A typical nuclear power plant generates about 20 metric tons of used nuclear fuel per year. The problem is that this spending fuel is highly radioactive and potentially dangerous.

You should know the implicit meaning of the prefixes of units of measurements. Let's take for example, the unit of meters. When you say kilometers, that would be 10³ of a meter. When you say megameters, that's 10¹⁰ of a meter. So, if a unit is 5.69×10¹⁰ meters, you can just express that into 5.69 megameters.
Answer: The law of corresponding states is an empirical law according to which the equations of states for real gases are similar when these gases are expressed in reduced temperature, pressures, and volumes at critical point.
