Draw an orbital overlap diagram to represent the bonding in ammonia, nh3

The alkali metals (group 1) consist of lithium (3), sodium (11), potassium (19), rubidium (37), cesium (55), and francium (87). they are soft, metallic solids with low densities and low melting points. based on the data shown in figure 1, how many valence electrons do alkali metals share?

In this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced?

May someone me with these science questions
