To determine which atom contains only three valence electrons, we first need to understand what valence electrons are. Valence electrons are the electrons located in the outermost shell of an atom. They play a crucial role in chemical bonding and reactions. Now, let's analyze the options provided: Li (Lithium): Lithium has

Since one mole of the particles of a substance means that we have 6.023 × 1 0 23 6.023 times 10^{23} 6.023 × 1 0 23 particles of a substance (in this case, atoms), the smaller the number the moles of atoms of a substance, the smaller the number of atoms of a substance.. We concluded that 10 grams of Cs contain the smallest number of moles, so 10 grams of Cs contains the …
