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.

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 :)
As an electron moves farther from the nucleus, its energy increases. This increase in energy results in the electron being in a higher energy level or orbital. The electron's increasing distance from the nucleus leads to decreased attraction, causing it to have more potential energy.
The principal quantum number (n) defines the main energy level or shell of an electron in an atom. It determines the average distance of the electron from the nucleus, as well as the energy of the electron. The higher the principal quantum number, the higher the energy level and the greater the distance from the nucleus.

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 approximate distance an electron is located from the nucleus is measured by the concept of electron cloud or electron probability density. This concept is utilized in quantum mechanics to describe the distribution of the electron's probable locations within an atom.
An electron in a 2s orbital is on average closer to the nucleus.
Is called a shell. The first shell around the nucleus can hold a maximum of two electrons. While the second shell can hold a maximum of eight electrons.
Electrons exist in orbitals around the nucleus of an atom. It takes energy to knock an electron from the orbital it is in to an orbital a greater distance from the nucleus. The electron gives off energy when it falls closer to the nucleus. A Danish Scientist named Niels Bohr figured it out.
In an s orbital, the probability of finding an electron at a particular distance from the nucleus does not depend on the direction in which the distance is measured or the orientation of the orbital. This is because s orbitals are spherically symmetric, meaning the electron has an equal likelihood of being found at any distance from the nucleus in all directions.
