Physically put, the electron has more energy the farther ( higher ) it is from the nucleus. Simple potential energy. PE = mgh
decreases
Because if the radius is big, then the large distance affects the strenght of the electron with the nucleus. This also increases reactivity in non metals since it will be easier to take away the electron :)
if an electron gains enough energy it jumps to a higher energy level. when this happens the atom is in an "excited" state.
The farther an electron is from the nucleus of an atom, the more energy it has.
No. The greater distance from the nucleus the more energy an electron has.
The nucleus has a width on the order of 10^(-15) meters, while an electron is (on average) a distance of 10^(-10) meters from the nucleus. If you were to magnify the nucleus to the size of a baseball, the electrons would be orbiting at a distance of around 1000 meters. That is, there are about 50,000-100,000 nucleus diameters to the electron's average radius.
Attraction gets smaller.
Down a group, the number of shell increases and the electron enters into a different shell. Hence, the distance between the nucleus and valence electron increases and the nuclear attraction decreases

Shell
It would not depend on the direction with respect to the nucleus. The direction of the electron has no effect on the distance of the electron from the nucleus.

The farther an electron is from the nucleus of an atom, the more energy it has.
When a nucleus emits a beta particle (electron) it is a result of neutron decay. This decay will also release an antineutrino and a proton is left which increases the atomic mass by one thereby changing the element.
The atomic radius is the distance from the nucleus of an atom to the outermost orbital of electron.
No. The greater distance from the nucleus the more energy an electron has.
