Many elements combine with hydrogen(valence = 1) to give compounds called hydrides. use the position of an element in the periodic table to deduce its valence. write formulas for these hydrides without using subscripts, for example xh3. if no hydride forms, write "none". what is the formula of the hydride formed by sulfur? what is the formula of the hydride formed by potassium ? ||

Will give brainliest it is a lab from k12 here is the linkfor each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. type your answer here. (score for question 3: of 5 points) were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. type your answer here. (score for question 4: of 5 points) make a general statement about the reactivity of the metals in this experiment. type your answer here.

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?
