Actinium's atomic number is 89. Thus, it has 89 protons and, to keep it neutral, 89 electrons. Filling in the first 89 electron orbitals gives us an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 5d10 6p6 4f14 7s2 6d1. When you shorten that to [Rn] 6d1 7s2, it becomes clear that actinium has 3 valence electrons, 1 in the 6d shell and 2 in the 7s shell.
Indium has 3 valence electrons.
8 valence electrons- 1s22s2p63s2p6
There are 3 valence electrons in an atom of aluminium.
There are no valence electrons.
Actinides are highly reactive elements due to their large atomic size and ability to accommodate a wide range of oxidation states. They can form compounds with various organic and inorganic molecules, and exhibit complex chemical behavior due to their partially filled f-orbitals. Actinides are also radioactive, which adds to their reactivity in terms of nuclear decay and radiation effects.

An atom can have anywhere from 1 to 8 valence electrons. The number of valence electrons. Elements in the first column of the Periodic Table have one electron, those in the second have two. Those in the large block ins the middle (the transition elements, the lanthanides, and the actinides are generally considered to have two valence electron , though they have a property called variable valence. The trend of valence electrons continues in the block on the left side (the last six columns). The first column in this block has six valence electrons, and so forth until the last column in which the elements have eight valance electrons, except for helium which has two.
