The atomic number of Lithium is 3, its mass number is 7. - Toppr Therefore, the number of protons and neutrons present in a Li atom is 3, and 4 respectively. $$(b)$$ Since Li is a neutral atom thus, the number of electrons will be equal to the number of protons that is 3.
A doubly ionised Li atom is excited from its ground state (n ... - Toppr A doubly ionised., lithium atom 1% hydrogen like with atomic number z = 3. Find the wavelength of radiation required to excite the electron in L i 2 + from the first to the third Bohr orbit. (Given : 1 R H = 912 ˇ A ]
019 The atomic number of Lithium is 3. its mass number is 7. a How many lithium atoms are present in a unit cell with edge length 3.5 ˚ A and density 0.53 g c m − 3? (Atomic mass of Li =6.94) (Atomic mass of Li =6.94) View Solution
A double ionized lithium atom is hydrogen-like with atomic ... - Toppr A double ionized lithium atom is hydrogen-like with atomic number 3. (a) Find the wavelength of the radiation required to excite the electron in L i + + from the first to the third Bohr orbit. (Ionization energy of the hydrogen atom equals 13.6 e V)\ (b) How many spectral lines are observed in the emission spectrum of the above excited system?
In the lithium atom screening effect of valence shell electron ... - Toppr The ratio of atomic numbers of two elements A and B is 1 : 2. The number of electrons present in the valence shell (3rd) of A is equal to the difference in the number of electrons present in the other two shells.
How does a lithium cation compare to a lithium atom? - Toppr In terms of size, we say lithium cation is smaller than lithium atom ion. This is because lithium cation was formed by losing electrons (while it was a lithium atom).
The wavelength of radiation required to excite the electron from the ... A double ionized lithium atom is hydrogen-like with atomic number 3. (a) Find the wavelength of the radiation required to excite the electron in L i + + from the first to the third Bohr orbit. (Ionization energy of the hydrogen atom equals 13.6 e V)\ (b) How many spectral lines are observed in the emission spectrum of the above excited system?

An atom contains 3 protons, 3 electrons and 4 neutrons. Find A lithium atom contains 3 protons in its nucleus irrespective of the number of neutrons or electrons. Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always 3. The mass number, however, is 6 in the isotope with 3 neutrons, and 7 in the isotope with 4 neutrons
