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.
Is lithium a hydrocarbon?
No, lithium is not a hydrocarbon. Lithium is a chemical element that belongs to the alkali metal group on the periodic table. Hydrocarbons are compounds consisting of hydrogen and carbon atoms.
What is the symbo for element S2d1?
The element with the electron configuration 2s1 is lithium (Li). However, there is no element with the electron configuration S2d1 as "S" and "d" are not valid subshells in the electron configuration notation based on the periodic table.
Is lithium a pure element?
No - the lightest elements are hydrogen and helium. Although lithium is a lightest metal and the lightest element that is a solid at room temperature.
What atom loses its electron easily is it carbon potassium lithium or hydrogen?
Potassium. This can be seen by the potassium setting itself on fire in water. Can lithium, carbon or hydrogen do that?
Which element is smallest Excluding H and He element in the periodic table?
Lithium is the smallest element in the periodic table if Hydrogen and Helium are excluded.
Which element has one valenece electron?
Hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium have one valence electron.
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 lightest element in the universe?
Hydrogen. It is the lightest element in the known universe.
Which element has the smallest anion radius?
Fluorine has the smallest anion radius among the elements.
What element has the electron configuration 1s2 2s1?
Lithium (Li) has the electron configuration 1s2 2s1.
What is the the most common charge of the element Li?
If you look at the periodic table, Lithium (Li) is in the first column, group 1A, under Hydrogen, and above Sodium (Na). These elements are typically "electron donors" to fill out their electron shell. So, Lithium, Hydrogen, and Sodium all would typically ionize with +1 charges.
Which element has one 2s electron?
Lithium
Which atom is the lightest?
Hydrogen is the lightest element. The isotope protium is the lightest kind of hydrogen atom.
What two elements have the smallest atomic masses?
hydrogen and lithium
Which element between lithium potassium rubidium and cesium has the smallest ionization energy?
T he smallest first ionization energyis for lithium.
How many valence electrons are in Lithium?
Lithium has 1 valence electron.
