What does the ionization of a hydrogen atom produce?
Ionised hydrogen, commonly called HII (pronounced H-two), is a hydrogen atom that has lost its electron and is now positively charged. It is easily detected at optical wavelengths as it releases a photon of wavelength 656.3 nm when it recaptures an electron and returns to its neutral state.
What happens when a hydrogen atom absorbs electromagnetic radiation?
(a) When a hydrogen atom absorbs a photon of light, an electron is excited to an orbit that has a higher energy and larger value of n.
How does the Bohr model of the hydrogen atom explain the spectrum of hydrogen?
Bohr’s model explains the spectral lines of the hydrogen atomic emission spectrum. While the electron of the atom remains in the ground state, its energy is unchanged. When the atom absorbs one or more quanta of energy, the electron moves from the ground state orbit to an excited state orbit that is further away.
Which statement is correct for the emission spectrum of the hydrogen atom?
Which statement is correct for the emission spectrum of the hydrogen atom? The lines are produced when electrons move from lower to higher energy levels. The lines in the visible region involve electron transitions into the energy level closest to the nucleus.
What is ionized hydrogen molecule?
The dihydrogen cation or hydrogen molecular ion is a cation (positive ion) with formula H + 2. . It consists of two hydrogen nuclei (protons) sharing a single electron. It is the simplest molecular ion.
How do you find the ionization energy of a hydrogen atom?
For hydrogen, first orbit energy is –2.18 × 10– 18 J/atom (or – 1312.3 KJ/mole), and the ionization energy is + 2.18 × 10–18 J/atom (or + 1312.3 KJ/mole).
What is the absorption spectrum of hydrogen?
The absorption spectrum of hydrogen shows the results of this interaction. In the visible part of the spectrum, hydrogen absorbs light with wavelengths of 410 nm (violet), 434 nm (blue), 486 nm (blue-green), and 656 nm (red). Each of the absorption lines corresponds to a specific electron jump.
Why does hydrogen atom produce so many spectral lines even though it contains one electron?
Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the shells causes different wavelengths to be released… hence, mono-electronic hydrogen has many spectral lines.
What does the atomic emission spectrum of hydrogen look like?
A hydrogen discharge tube is a slim tube containing hydrogen gas at low pressure with an electrode at each end. If a high voltage (5000 volts) is applied, the tube lights up with a bright pink glow. This is a small part of the hydrogen emission spectrum. …
Which statement explains the emission line spectrum of electromagnetic radiation?
The emission spectrum of a chemical element or compound is the ‘range’ of frequencies of electromagnetic radiation (emitted by an atom or molecule passing from a high energy state (excited state) to a lower one or configuration with less energy).
What is the ionization energy of hydrogen?
The cited value for the ionization energy of hydrogen is actually 1312 kJ mol−1. My guess would be that the difference between the two results was caused by the value I used for Avogadro’s constant and by rounding.
How many molecules of water are ionized by radiation?
Between three and four water molecules are ionized for every 1.6 x 10 -17 joules of energy absorbed in the form of ionizing radiation. The H 2 O + ion should not be confused with the H 3 O + ion produced when acids dissolve in water.
What is the energy required to remove an electron from hydrogen?
E = 2.181 ⋅ 10−18 J This means that in order to remove the electron from the ground state of a hydrogen atom in the gaseous state and create a hydrogen ion, you need to supply 2.181 ⋅ 10−18 J of energy. This means that for 1 atom of hydrogen in the gaseous state, you have H(g) +2.181 ⋅ 10−18.J → H+ (g) + e−
What type of radiation can remove electrons from a water molecule?
Radiation that carries more energy than 1216 kJ/mol can remove an electron from a water molecule, and is therefore called ionizing radiation. The table below contains estimates of the energies of various kinds of radiation. Radio waves, microwaves, infrared radiation, and visible light are all forms of non-ionizing radiation.
