As you go across a period, radius shrinks because you are adding protons. The added positive charge increases pull on the electron shells.
As you go down a group, radius gets larger because you are increasing shells of electrons. This increases shielding of the nucleus' positive charge, so the electrons are not pulled in as much.
Answer:
Explanation:
A cold front is a transition zone from warm air masses to cold air masses. We use weather elements to identify cold fronts.
- Temperature: Since air moves from warm masses to cold masses, the air in a cold front is at different temperatures. The air behind a cold front is warm while the one ahead is cold. This implies that within a cold front is at different temperatures.
- Precipitation: Prior to the passing of cold front, precipitation is usually rife with low showers. A coldfront in itself is usually accompanied by heavy rainfall full of thunderstorms and lightening. After a coldfront, the showers steadies and decreases.
- Pressure changes: before a coldfront, the atmospheric pressure decreases steadily. When the front arrives, the pressure further lowers with a sharp increase thereafter. After the front, the pressure can continue to increase.

The scientist that developed the equation of wave mechanics is <span>Erwin Schrodinger that combined the works of Bohr and de Broglie. The electron
was a three dimensional wave circling the nucleus in a whole number of wavelengths
allowing the waveform to repeat itself as a stable standing wave (it can absorb
energy form a nearby source which is oscillating at a proper frequency)
representing the energy levels of Bohr model. He also said that Broglie’s model
was correct about the matter waves and the electrons are located in the atomic
space according to standing wave frequencies.</span>
Nuclear fission is the process of which a large nucleus splits into two smaller nuclei with the release of energy and neutron. In simpler words, nuclear fission is the process in which a nucleus is split into two smaller fragments or pieces (nuclei) and so energy and neutrons are released. The resulting pieces of this fission process have less combined mass than the original piece (nucleus) and the missing was is converted into nuclear energy.
