The answer is the last option.
Answer is: 1 × 10⁻¹⁰ meter or 0.0000000001 meter.
The atomic radius is a measure of the size of the atom.
It is distance from the center of the nucleus of atom to the boundary of electron cloud.
The radius of atoms is between 30 and 300 pm (10⁻¹² m) or between 0.3 and 3 angstroms (10⁻¹⁰ m).
The radius generally decrease along each period of the Periodic table.
Answer: Option B
Explanation:
Cell membrane can be defined as the outermost covering of the cell which allows the movement of particles across membrane. The particles are allowed to move from inside of the cell to the outside of the cell and from outside to inside of the cell.
This kind of a membrane is known as selectively permeable which allows the movement of certain molecules only.
hence, the correct answer is option B
