What else can I help you with?
Hydrogen lithium and sodium all have one valence electron Which element has the smallest atomic radius?
Among hydrogen, lithium, and sodium, hydrogen has the smallest atomic radius because it has the fewest number of electron shells and the smallest number of electrons, leading to a smaller atomic size.
What is the size of sodium's atom?
Atomic size of sodium is 186
How would you arrange these elements in order of decreasing atomic size sulfur chlorine aluminum and sodium?
Sodium > Aluminum > Chlorine > Sulfur. Atomic size generally increases as you move down a group on the periodic table and decreases as you move across a period from left to right. Sodium is in the same period as chlorine but is a metal, so it has a larger atomic size. Aluminum is in the same period as sulfur but is a metal, so it has a larger atomic size. Chlorine is a non-metal and smaller than both aluminum and sodium. Sulfur is a non-metal and the smallest among the four elements listed.
What has the smallest atomic radius out of hydrogen sodium and lithium?
Helium has the smallest atomic radius out of hydrogen, sodium, and lithium. This is because helium has a full electron shell, leading to a smaller effective nuclear charge that pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
What is the smallest alkali earth metal?
Beryllium is the smallest alkali earth metal in terms of atomic size and atomic number.
What is the size of sodium atom?
The approximate size of a sodium atom is about 0.186 nanometers (nm) in radius. Sodium is a relatively large atom compared to hydrogen or helium because it has more electrons and protons, leading to a larger atomic radius.
Which is the smallest element in the periodic table?
Hydrogen has the smallest atomic size of any element.
Which element has the smallest atomic size from first 4 periods?
Helium has the smallest atomic size among elements in the first four periods of the periodic table. It has the smallest atomic radius due to its high effective nuclear charge and low electron-electron repulsion.
Which of the elements sodium calcium potassium and magnesium has the smallest first ionization energy?
Potassium has the smallest first ionization energy among those elements listed. This is because potassium has the largest atomic size and the weakest attraction between its nucleus and outermost electron, making it easier to remove that electron.
What elements has the smallest atomic size K Ca Na Ar or Kr?
The element with the smallest atomic size is Argon (Ar) as it has the highest atomic number among the options given. Atomic size generally decreases from left to right across a period in the periodic table.
How does its potassium atomic radius compare to that of sodium?
The atomic radius of potassium is larger than that of sodium. This is due to the increase in atomic size as you move down a group in the periodic table, with potassium being located below sodium.
What has the smallest atomic radius Na Mg Cl Al?
The smallest atomic radius is found in Cl (Chlorine), followed by Al (Aluminum), then Na (Sodium), and finally Mg (Magnesium). The trend typically follows an increase in atomic radius from right to left across a period and from top to bottom down a group on the periodic table.
