How many electrons may be accommodated in the first three energy levels?

2 answers:

3 0

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. Some points will be nice

The first energy level can hold 2 electrons after that all other energy levels hold 8 electrons which means 3 energy levels can hold 18 electrons 2+8+8=18

What is the movement of water up a narrow tube due to attractions with the surface of the tube called? capillary action meniscus

Shtirlitz [24]

The attraction mediated flow of water in the narrow tube has been termed as Capillary action. Thus, option A is correct.

The process of flowing up of liquid with the attraction force between the molecules and the surface has been achieved with the surface characteristics.

<h3>Movement of water in a narrow tube</h3>

The surface has the force of attraction with the flowing liquids in the sample. It results in the increased surface interaction, and the liquid flows up in the tube against gravity.

The movement of the liquid in the water through a narrow tube has been termed as capillary action. Thus, option A is correct.
