How many valence electrons are in an atom with the electron configuration in example a? example a: 1s22s22p63s23p4 6 4 2 18

6.

Explanation:

Valence electron may be defined as the electrons present in the outermost shell. The valence electron has the ability to lose or gain the other electron and also determines the chemical property of the element.

The outermost electrons can be calculated by looking at the outermost shell. In the given example 1s22s22p63s23p4, the number of valence electrons are 6 ( the sum of electron present in the 3s and 3p orbitals.

Thus, the correct answer is option (1).

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
