Hydrogen because it has one electron in one energy level and is needed to make water (essential liquid).
Gallium is the element has three electrons in energy level n = 4.
The energy level of an element is what Period it is in. For example, berylium is in Period 2, so that means it has 2 energy levels.
Calcium has electrons in the 4th energy level. The only liquid that has valence electrons in energy level 4 would be BROMINE.
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
Lithium
5 atoms are located in the second energy level if the first energy level has 7.
Gallium is the element has three electrons in energy level n = 4.
The energy level of an element is what Period it is in. For example, berylium is in Period 2, so that means it has 2 energy levels.
The things that happens to the energy level of solid as it become liquid water is that the liquid has more energy than solid do. Simple as that! BY: ANONYMOUS :)
All of them.
hydrogen
Calcium has electrons in the 4th energy level. The only liquid that has valence electrons in energy level 4 would be BROMINE.
Hydrogen is the smallest element. It has only 1 energy level. It is a gas element.
1s
The element carbon
nobel gases has few electron in the outer energy level
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
