If an element contains 8 electrons, then there would be 6 electrons that will be placed in the 2nd valence shell. Each shell in an atom can only take up a fixed number of electrons. For the first shell, only two electrons can be found. For the second shell, it can hold up to 8 electrons. However, for this case only six electrons can be found since the others are found in the first shell.
Answer: Electric charges are of two general types: positive and negative.

It changes the boiling point of the water, and it changes the freezing point of the water
Answer: Option (A) is the correct answer.
Explanation:
When there occurs no change in the chemical composition of a substance then it is known as physical property.
For example, mass, volume, density are all physical properties.
Since, the mass of an electron is negligible and an electron holds a negative charge.
Therefore, negatively charged particle with very little mass accurately describes the physical properties of electrons in atoms.
