How are electrons arranged in the atom?
Electrons are arranged around the atomic nucleus forming the electron clouds.
How many energy levels would electrons of hydrogen and helium fill?
1st energy levels only in which hydrogen will have only one electron whereas helium will have two electrons.
Bohr used the emission spectrum of hydrogen to support his idea that?
Each energy level corresponds to an exact amount of energy needed by the electron to orbit the nucleus. Transitions from a higher energy level to a lower energy level correspond to the difference in the energy needed for an electron to occupy those two energy levels. This difference creates the emission spectrum.
Who discovered that electrons go around the nucleus of an atom on energy levels?
Ernest Rutherford created the model of the atom with electrons orbiting the nucleus, Werner Heisenberg added the energy levels using his theory of Quantum Mechanics to explain why those electrons don't instantly spiral into the nucleus emitting x-rays and gamma rays destroying all atoms.
How does the energy of an electron change when the elctron moves closer to the nucleus?
the electrons moving closer to the nucleus have lower energy level.why?AnswerWhen atoms absorb energy, electrons move into higher energy levels, and these electrons lose energy by emitting light when they return to lower energy levels.It's like a sea saw, you go up, you get energy, go back down, lose it.please recommend me :D
How are electrons arranged in the atom?

According the the Bohr model of an atom the single electron of a hydrogen atom circles the nucleus?
in specific energy levels -will
Characteristics of the series of levels surrounding the nucleus?
Energy levels or Energy
Who sugessted thatthe electrons orbited the nucleus in fixed energy levels?
Niels Bohr first suggested that electrons orbited the nucleus in fixed energy levels.
The energy levels around the nucleus hold?
Electrons
What is the Location of proton and neutrons?
Electrons -- in energy levels outside the nucleus. Protons in the nucleus. Neutrons in the nucleus.
What are quantized energy levels?
The concept of quantized energy levels, first proposed by Neils Bohr, states that electrons can only exist in certain possible energy levels, which he pictured as orbits around a nucleus since the energy of an electron is proportional to its distance from the nucleus.
Why cesium has a lower first ionization energy then rubidium?
Caesium has more electron levels than rubidium, because the electrons are further away the attraction between the outer electrons and protons in the nucleus is less. But that's not just the answer. There is also a thing called electron shielding, the negative charges, of the electrons in the energy levels closer to the nucleus, sort of repel the outer electrons so they can't get closer to the nucleus. Since the electrons are further away and have the attraction from the positively charged nucleus reduced, it takes less energy to break the attraction for caesium than rubidium.
How is it possible that the elements get smaller as you move left to right across a period on thetable?
Each element from left to right gains a proton, which increases the pull of the nucleus on it's electrons. Each element also gains an electron, but the electrons are added to the same or a lower energy level..only when you go down a group do the number of energy levels increase. This pull of the nucleus causes the atomic radius to decrease because the electrons are pulled in tighter by the stronger nucleus. As you go down, atoms get bigger because of added energy levels. Energy levels on the outside are shielded from the nucleus by electrons on inner levels, so they range further away from the nucleus.
What is the location of electrons protons and neutrons?
Electrons -- in energy levels outside the nucleus. Protons in the nucleus. Neutrons in the nucleus.
What is the term for an atom whose electrons have the lowest possible energies?
The term for an atom whose electrons have the lowest possible energies is "ground state." In this state, electrons are in their lowest energy levels or orbitals, closest to the nucleus. Excited states refer to when electrons are in higher energy levels, further away from the nucleus.
What are the energy levels of the electron clouds?
those closest to the nucleus
