lithium (Li)
No, H+ ions are the smallest (proton size), hydrogen atoms and even Li+ ions are smaller than Li atoms.
Among potassium (K), oxygen (O), sulfur (S), and lithium (Li), lithium would have the smallest ionic radius. This is because lithium has the highest effective nuclear charge, resulting in a stronger pull on its outermost electrons, leading to a smaller ionic radius.
K has a larger atomic radius than Li. This is because atomic radius generally increases down a group in the periodic table, so potassium (K) being below lithium (Li) in Group 1 will have a larger atomic radius.
Francium (Fr) down a group, the radius increases.
C forms a covalent network solid in the form of diamond. CO2 forms a molecular solid due to the presence of covalent bonds between the carbon and oxygen atoms. Li and O2 do not typically form covalent network solids; Li usually forms metallic solids and O2 forms a molecular solid.

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.

Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
no
From the given elements, Mg has the largest atomic radius, hence the size.
K has a larger atomic radius than Li. This is because atomic radius generally increases down a group in the periodic table, so potassium (K) being below lithium (Li) in Group 1 will have a larger atomic radius.
This bond is ionic.
Francium (Fr) down a group, the radius increases.

C forms a covalent network solid in the form of diamond. CO2 forms a molecular solid due to the presence of covalent bonds between the carbon and oxygen atoms. Li and O2 do not typically form covalent network solids; Li usually forms metallic solids and O2 forms a molecular solid.
