The correct answer is option B. i.e. the number of protons is increased.
In beta-particle emission, a neutron is changed into proton, electron and electron neutrino. The electron is emitted as beta particle and the proton remains inside the atom. Thus, the mass number remains same but the atomic number increases by one.
Group.
Block.
Atomic number.
Electron configuration. .
Melting point.
Boiling point.
Sublimation.
<span>Yes, the material will float because it has a lower density than that of water.
A material will float if it has a lower density than that of the liquid it's placed in. So let's first calculate the density of this new material.
Density is simply mass per volume, so doing the division.
2.0 g / 3.0 cm^3 = 0.67 g/cm^3
The density of water is 1.0 g/cm^3 and since the density of the new material is less at 0.67 g/cm^3 it will float.</span>
Answer:
Saturn's rings are made up of ice, dust, rocks, moons and other satellite that orbit the gas giant as its equator, where gravity is strongest.
