If an element contains 8 electrons how many electrons will be placed in the 2nd valence shell?
RideAnS [48]
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.

Which set of characteristics accurately describes the physical properties of electrons in atoms
zloy xaker [14]

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.
