Why Does The Ionic Radius Increase As The Atomic Number Increases?

Atomic number of an atom is equal to the number of protons or number of electrons present in the atom. When an electron and a proton is added to an atom, the atomic number of the atom increase. With increase in the atomic number the ionic radius of the atom also increases. The ionic radius of the atom increases because, when a proton is added to the nucleus a force of repulsion increases between the protons of the nucleus. Due to this repulsion they move away from each other. Similarly, beside the addition of an electron, the electrons present in the atom repel each other. As a result, the ionic radius of the atom increases. Moreover, surrounded by some elements the ionic radius decreases with increase in atomic number.

Describe The Exponential Smoothing Method?
Exponential smoothing is also known as moving average technique. It is applied to time series data. This process is used for making forecasts. The time series data i.e. used for exponential smoothing is the sequence of observations with time. Exponential smoothing is widely applied in financial markets. Companies are also...

Is There Any Life Found On Mars?
Not yet but they havent explored it but there r large river bed to hold water Not yet, there is no proof, as they haven't thoroughly explored Mars at all, but here is known to be water on Mars, which could be a sign of life.

For how much time will soil later?
Until the sun dies. About another 4-6 billion years. The sun's demise will include it's expansion in size past the earth's orbit, engulfing top soil. That is the outer estimate that I have heard. I guess earth could be smashed by an foreign baulk (i.e. a comet) and end...
