Size of the nucleus increases with number of nucleons. As size increases, volume increase (le mass number increases).
Calculate radius of 13Al 27 nucleus. The constant R0=1.2 fermi.

When the size of an atom increases, does the attraction of the nucleus on the outermost electron increase or decrease?

The radius of an air bubble is increasing at the rate of 1/2cm//s . At what rate is the volume of the bubble increasing when the radius is 1 cm?

The radius of an air bubble is increasing at the rate of 1/2 cm / s. At what rate is the volume of the bubble increasing when the radius is 1 cm ?

Which of the following statements are related to Boyle's law? a. When pressure increases volume decreases. b. When temperature increasen, volume increases. c. If P is pressure and V the volume N then P xxV is a constant. d. At constant temperature and pressure the volume of a gas is directly proportional to the number of molecules.

Consider following statements, I. The size of the lanthanide M^(3+) ions decreases as the atomic number of M increases. II. Electronic spectra of lanthanides show very broad bands. III. As with transition metals, coordination number six is very common in lanthanide complexes. Which of the statements given above is/are correct?

The radius of a cylinder increases at a rate of 1 cm/s and its height decreases at a rate of 1cm/s. Find the rate of change of its volume when the radius is 5 cm and the height is 15 cm. If the volume should not change even when the radius and height are changed, what is the relation between the radius and height?

Assertion : As the distance of the shell increases from the nucleus its energy level increases Reason : The energy of a shell is E_(n)alpha(-1)/n^(2)

Statement 1 : the nuclear isomers are the atoms with the same atomic number and same mass number, but with different radioactive properties. Statement : 2 The nucleus in the excited state will evidently have a different half-life as compared to that in group state.
