The lines at the ultraviolet end of the hydrogen spectrum are known as the lyman series wich electron transitions within an atom are responsible for these lines?

The series of lines in an emission spectrum caused by electrons falling from energy level 2 or higher (n=2 or more) back down to energy level 1 (n=1) is called the Lyman series. These emission lines are in the ultra-violet region of the spectrum.

How many valence electrons in H2 atom?
H2 is not an atom, it is a diatomic molecule. Each hydrogen atom has 1 valence electron. When two hydrogen atoms covalently bond to form an H2 molecule, there are two valence electrons being shared by the two atoms.
You have 1 electron 1 proton and 1 neutron. What are you?
You are an atom of heavy hydrogen, or deuterium. Most hydrogen has one proton and one electron, which form a neutral atom. But once in a while, a neutron will stick to the proton, and then the atom, which is still hydrogen (it has just the one proton) will be about twice as massive as "regular" or "common" hydrogen. It is another isotope of hydrogen called heavy hydrogen or deuterium.
How do you use the word electron in a sentence?
The electron has a negative charge and orbits the positively charged atomic nucleus. Many compounds are made possible by electron sharing between elements.
How many valence electrons does HBr have?
Hydrogen has 1 valence electron. Bromine has 7 valence electrons. When hydrogen and bromine react, the bromine atom 'steals' the hydrogen atom's only electron. The hydrogen atom then has no electrons and the bromine atom has 8 valence electrons. The two atoms are now ions because their number of protons does not equal their number of electrons. The bromine atom is now a bromide anion and the hydrogen atom is now a hydrogen cation (a proton). The two ions remain together, ionicly bonded and together are called hydrogen bromide.
How do you explain the diagram that shows 4 energy levels of hydrogen - 1 at the bottom 4 at the top - the values are n4-0.85eV n3-1.51eV n2-3.4eV n1-13.6eV?
The diagram shows the ionization energies of hydrogen. The ionization energy for a ground-state electron in hydrogen is 13.6eV. Let's jump. An electron orbits an atom of hydrogen in as low an energy level as possible. That's the ground state of hydrogen. To tear that electron away, it takes some amount of energy. In this case, it takes 13.6eV to strip off that electron. But what if the electron is in the next higher allowable energy level because the gas it hot? In that case, it takes less energy to tear that electron away because you've got a "head start" owing to the fact that the electron is in a higher orbital than the ground state. And what if it's in the next higher allowable energy level? Or the next? Less and less energy is required to strip off the electron as it moves to higher energy levels. These are the ionization energies of hydrogen. These energy levels are specific to hydrogen. Each other element will have a different set if ionization energies associated with it. And with atoms with many electrons and complex electron structures, the problem can quickly become very complex.
When a hydrogen electron transitions from n equals 1 to n equals 4 is the energy of electron increased or decreased?
decreased
What is a hydrogen atom that has lost an electron and is responsible for producing properties of acid?
proton
Find the frequency of revolution of electron in the classical model of the hydrogen atom In what region of the spectrum are electromagnetic waves of this frequency?

What are the Electron Configuration of hydrogen?
Hydrogen electron configuration will be 1s1.
What is the difference between hydrogen and an electron?
Hydrogen is an element, the electron is a subatomic particle.
What has one electron?
Hydrogen
What are the orbits of hydrogen?
Hydrogen only has one electron orbit, as it only has one electron.
Who is lighter electron or hydrogen atom?
electron
What particle has the lowest mass number?
An electron. As the mass of an electron is 00000000000000000000000000000091 kg
Which is not a type of chemical bond covalent hydrogen electron or ionic?
which is not a type of chemical bond, covalent, electron, ionic, or hydrogen
Can hydrogen serve as the final electron acceptor of the electron transport chain?
No. Hydrogen's electronegativity is too weak. At 2.5 hydrogen does not have the electronegativity to pull electrons down the electron transport chain.
