We can bump the electron to a higher energy level, by shooting photons at it that have
just the right energy.
But if we try to look at it any closer than that ... to find out 'where' it is, what 'size'
it is, what 'direction' it's going, or how 'fast', first of all, there's no way to do that
without shooting photons at it which changes all of those things, but even worse
than that, the electron doesn't even look like a little pellet to us, it looks like a wave!

What subatomic particle is in constant motion around the nucleus?
Around the atomic nucleus orbit electrons.
What is the change in velocity other than speed what else?
change in velocity can also occur with change in direction as it is a vector with speed and direction; so a satellite may have constant speed but remaining in orbit has a centripetal acceleration; its direction is changing.
What is the work done by an electron revolving in a circular orbit of rdius r around the nucleus?
Here a centripetal force provided by electrostatic force of attraction acts on the electron towards the centre of orbit but motion is along the tangent to the circular orbit at ecah point. As force and displacement are in mutually perpendicular directions at each point, the work done is zero. E V SHAKKEER HUSSAIN
What is the work done by the field of a nucleus in a complete circular orbit of the electron. what if the orbit is elliptical?
Work done is always zero, whatever be the shape of the orbit because electron will be in the same energy state after it completes an orbit
How can you have acceleration without a change in velocity?
Turning is acceleration, and it doesn't affect your speed. One example of this is a satellite in orbit, it is always accelerating towards the Earth due to gravity, but the speed doesn't change because it's just turning in a circle around the Earth.
What controls a rocket ship in space?
Gravity is the biggest determining factor of the direction of motion of a vessel in orbit, and the rocket's engines are used to change the shape of that orbit.
In an s orbit the probability of finding an electron a particular distance from the nucleus does not depend on?
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 transition of an electron from outer orbit to inner orbit involves a change in its what?

How does the electron's energy change as the orbit of the electron increases?
The farther an electron is from the nucleus of an atom, the more energy it has.
What subatomic particle is in constant motion around the nucleus?
Around the atomic nucleus orbit electrons.
What should be the angle between the direction o foce and the direction of motion of a body so that the work done is zero?
Work is zero when the force is perpendicular to the direction of motion, as it is, for example, in a circular gravitational orbit.
The transition of an electron from an outer orbit to an inner orbit involves the change in its?

Is it possible for electrons to orbit the nucleus with any possible energy?
No. Electrons will orbit around an atom only at specific energies (which change depending on the atom's atomic number and atomic mass). If you try to use a photon to change the energy of an electron and move it to another orbit path (or "energy level"), and the photon has the wrong energy in it, the electron won't change its orbit.
What happens if an atom is supplied with excess energy?
An electron may change to an excited state, and an electron may move to a higher orbit.
How would the motian of the moon change if there where no gravity?
The motion of the Moon would change from an elliptical orbit to a straight line.
What planet was used to explain retrograde motion?
Retrograde motion is motion in the opposite direction. In the case of celestial bodies, such motion may be real, defined by the inherent rotation or orbit of the body, or apparent, as seen in the skies from Earth.
In which direction do we orbit the Milky Way?
Looking from the Galactic north pole, we are orbiting around the Galactic centre in a clockwise motion.
