How many protons does a lithium atom have?
Based on the atomic number of lithium there are three protons in a lithium atom.
What is the element with the Neutron number 44.96?
You can't have 0.946 of a neutron. You've either got a whole neutron or you don't. So the answer is "there is no element with a neutron number of 3.946".The average number of neutrons in lithium is close to that. Somewhere between about 7.5% and 3.75% of lithium atoms have 3 neutrons; the rest have 4. That nicely brackets an average of 3.946 (which would correspond to 5.4% 6Li)
Can you name the primary elements of nature?
Hydrogen, helium, lithium... See a periodic table for the full list.Hydrogen, helium, lithium... See a periodic table for the full list.Hydrogen, helium, lithium... See a periodic table for the full list.Hydrogen, helium, lithium... See a periodic table for the full list.
What elements is used to make solar panels?
the answer is nickel, copper, and lithium, the lithium is used for containing the electrical charge.
Protons in a lithium ion?
In an ion your protons do not change it will always stay the same. So in this case Lithium would hae three protons
The line spectrum of lithium has a red line at 670.8 calculate the energy of a photon with its wavelength?
2.93x10^-19 Joules first use the v=c/h formula to find frequency then use the energy formula to find energy.
What is the wavelength of light emitted during a transition from the 4d orbital to the 2p orbital in Lithium?
Two step process. First this formula finding period, which is Hertz. (s -1)( Z number lithium = 3 )Hertz = (3.29 X 1015 s -1)*(Z2)*[1/Nf2 - 1/Ni2]Hertz = (3.29 X 1015 s -1)*(32)*[1/22 - 1/42]Hertz = (3.29 X 1015 s -1)*(9)*(1/4 - 1/16)= 5.55 X 1015 Hertz------------------------------now,Wavelength = speed of light/HertzWavelength = 2.998 X 108 (m/s)/5.55 X 1015 Hertz (s -1)= 5.40 X 10 -8 meters================== ( 54 nanometers ????? Seems unreasonable, but the formulas and work check )
What color does lithium burn?
Lithium compounds such as lithium nitrite produce a strong red when heated strongly in a Bunsen burner. You can see this by searching for lithium flame colour on youtube.com.You can see its spectrum on wikipedia.
What colour flame do you get when you burn lithium chloride?
When you burn lithium chloride, or any other lithium salt, you get a crimson flame, due to the positive lithium ions. The heat from burning the substance excites the outer electrons of the lithium ions to higher energy levels, when they drop back to the ground state, energy is released as light, and the wavelength of that light corresponding to that drop is crimson, hence we see a crimson flame.
Why is a lithium nitrate flame and a lithium chloride flame the same color?
Lithium nitrate and lithium chloride flame tests produce the same color because it is the lithium electrons that are raised to a higher energy level and then drop back down to their ground state. Any ionic compound containing lithium will give the same results. Flame tests are used to show the color and spectrum of the element as its electrons are raised to a higher energy level and then fall back to their ground state.
What is the approximate color of light emitted by heated LiCl?
The lithium will emit a bright red wavelength of light. This is a result of lithium atoms oscillating back and forth between their ground and excited states, absorbing and releasing quanta of energy of as their electrons jump up and fall back down through the energy levels.
How many nuetrons is in lithium?
4 neutrons in the most stable isotope of lithium (3Li7)
What has the author Rahim Koohi-Fayegh written?
Rahim Koohi-Fayegh has written: 'Neutron spectrum measurement in a beryllium-lithium fluoride assembly using an NE 213 scintillator'
What compound name is LiBr?
Lithium Bromine
Calculate the formula mass for lithium chloride?
The relative formular mass for Lithium Chloride is 42.5 This is the sum of the relative atomic masses of Lithium-7 and chlorine-35.5.
What are other names for lithium?
lithium is lithium
What is the name for Li2O?
lithium hydroxide + carbon dioxide --> lithium bicarbonate
