Fluorine (F) has the smallest atomic radius among the elements lithium (Li), oxygen (O), carbon (C), and fluorine (F). Atomic radius generally decreases across a period from left to right due to increasing nuclear charge, which pulls electrons closer to the nucleus. Since fluorine is located further to the right in the Periodic Table compared to the others, it has the smallest atomic radius.
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
From the given elements, Mg has the largest atomic radius, hence the size.
Among the elements Li (lithium), O (oxygen), C (carbon), and F (fluorine), lithium has the largest atomic radius. This is because atomic radius generally decreases across a period from left to right due to increasing nuclear charge, which pulls electrons closer to the nucleus. Lithium, being in Group 1 and the first period, has fewer protons and electrons than the other elements, resulting in a larger atomic size.
Of the elements listed by atomic symbol, Cs has the largest atoms.
The four atoms listed from smallest to largest radii are helium (He), lithium (Li), sodium (Na), and potassium (K). Helium has the smallest atomic radius due to its position at the top of the periodic table and its high effective nuclear charge. As you move down the group from lithium to potassium, the atomic radius increases because additional electron shells are added, resulting in a larger size.
No, H+ ions are the smallest (proton size), hydrogen atoms and even Li+ ions are smaller than Li atoms.
Rb
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.
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
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.
From the given elements, Mg has the largest atomic radius, hence the size.
Among the elements Li (lithium), O (oxygen), C (carbon), and F (fluorine), lithium has the largest atomic radius. This is because atomic radius generally decreases across a period from left to right due to increasing nuclear charge, which pulls electrons closer to the nucleus. Lithium, being in Group 1 and the first period, has fewer protons and electrons than the other elements, resulting in a larger atomic size.
The element with the longest covalent radius among Li, B, N, and F is Li. This is because as you move down a group in the periodic table, the atomic radius increases due to the addition of new electron shells. The covalent radius generally follows this trend.
Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
Of the elements listed by atomic symbol, Cs has the largest atoms.
Rb (rubidium) is the largest element among K (potassium), Rb (rubidium), Na (sodium), and Li (lithium). This is because as you move down a group in the periodic table, the atomic size increases due to the addition of more electron shells.
No, the atomic radius of neon (Ne) is smaller than that of lithium (Li). This is because as you move across a period in the periodic table, the atomic radius decreases due to increasing nuclear charge and stronger attraction for electrons.
