They each have 1.
Li- one
K- one
Lithium (Li) has 1 valence electron. It is in the same 'family' as Sodium (Na) and Potassium (K)
Potassium atom has 1 valence electron
Hydrogen (H) only has one electron. If you are talking about valence electrons, all of the elements in group 1A on the periodic table have one valence electron (H, Li, Na, K, Rb, Cs and Fr).
Elements in the 1st group have 1 valence electron. So they are likely to donate 1 electron to get more stable. potassium, rubidium and cesium are likely to donate 1 electron.

Both lithium and potassium have one valence electron

Hydrogen (H) only has one electron. If you are talking about valence electrons, all of the elements in group 1A on the periodic table have one valence electron (H, Li, Na, K, Rb, Cs and Fr).
Just one valence electron. The electron configuration for K-42 is 2-8-8-1, meaning that there is one electron in the outermost "shell" of the atom.
Elements in the 1st group have 1 valence electron. So they are likely to donate 1 electron to get more stable. potassium, rubidium and cesium are likely to donate 1 electron.

A neutral potassium atom has 19 electrons in total and 1 valence electron.
It has one electron in its valence orbital (s and p orbitals) like also all alkali metals have (Li, Na, K etc).
Just 1 valence electron in K (number 19, period IV, group 1)(Its electron configuration is 4s1, in which 4:means shell number 4, s: means s-orbital, 1: means 1 electron)4s1your answer is one valence electron
The outer shell contains 1 electron, ns1 Li [He] 2s1 K [Ar]4s1
