1s²
Explanation:
The predicted electron configuration of Helium 1s².
Helium is an element with atomic number of 2. it is located on the last group on the periodic table.
- Electron distribution into the energy levels or sublevels of atoms can be shown using electronic configurations.
Here, the two electrons in Helium fills the first energy level with s-sublevel first.
The maximum number of electrons in the sub-level is 2: this gives the 1s² configuration.

Yes it is. Copper is the same mass and volume. Plus all pennies are made of copper
Water and dimond are the 2 pure substances
The investigation using solid and liquid water to show that thermal energy is not the same as temperature is:
- Place a glass of water and a lake and both should be at the same temperature, find out if do they have the same amount of total thermal energy.
<h3>What is the response to the experiment above?</h3>
The response is No, because the lake is known to have a lot more particles than the glass of water and so they will not have the same thermal energy.
Note that the temperature is seen as the an average and thermal energy is seen to be the total. A glass of water can be able to have the same temperature as what we call Lake Superior, but the lake has a lot of thermal energy due to the fact that the lake has a lot of water molecules.
So the investigation using solid and liquid water to show that thermal energy is not the same as temperature is Place a glass of water and a lake and both should be at the same temperature, find out if do they have the same amount of total thermal energy.
