The substance, or the average energy. During the time from point D to point E, the liquid
. By point E, the substance is completely in the
liquid
phase. During the phase change, between minutes 13 and 18 (D-E), the energy given to the substance increased the
energy of the the particles, which
the intermolecular forces of attraction. With the intermolecular forces attracting them, the particles moved
each other.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

The real answer is keeping the world healthy so we won’t die

Answer : option a) 84explanation :

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
