Lithium-7 has 3 electrons.
Tantalum, with the chemical symbol Ta, is the chemical element with the atomic number 73.
There are 3 protons and 2 electrons present in a lithium ion.

In Li plus 1, the element is lithium (Li) which has 3 protons. Since it has a +1 charge, it means it has lost one electron, so it has 2 electrons.
Lithium (Li) has an atomic number of 3, meaning it has 3 electrons. When an atom loses electrons, it forms a positive ion, so for Li to become a Li+ ion, it must lose 1 electron, leaving it with 2 electrons.
li has atomic no. 3 so it has protons= 3 electrons- 3
Tantalum, with the chemical symbol Ta, is the chemical element with the atomic number 73.
Lithium is element #3, and it has 3 electrons.
There are 3 protons and 2 electrons present in a lithium ion.
Tantalum has 73 protons, 73 electrons, and isotopes of Tantalum include a varying number of neutrons. The most common isotope, Tantalum-181, has 108 neutrons.

In Li plus 1, the element is lithium (Li) which has 3 protons. Since it has a +1 charge, it means it has lost one electron, so it has 2 electrons.
Li+ ion has only 2 electrons in its only shell and they could be considered as both core and valence electrons.
A lithium ion (Li+) has one less electron than a neutral lithium atom. This means a lithium ion has 3 electrons.
Tantalum has 73 protons and electrons and its isotopes have 108 or 107 neutrons.
Lithium (Li) has an atomic number of 3, meaning it has 3 electrons. When an atom loses electrons, it forms a positive ion, so for Li to become a Li+ ion, it must lose 1 electron, leaving it with 2 electrons.
The decrease in radius from Li to Li and then to Li₂ can be attributed to the increasing effective nuclear charge experienced by the electrons. In lithium (Li), the single electron in the outer shell experiences minimal shielding from the inner electrons, leading to a larger atomic radius. However, when lithium forms Li₂, the two lithium atoms share electrons in a covalent bond, resulting in a stronger attraction between the nuclei and the shared electrons, which pulls the electron cloud closer and decreases the overall radius.
