Brainlies asap! 1. which statement is true about elements? they are finite in number. they are infinite in number. they combine to form atoms. they combine to form electrons. 2. which family in the periodic table has metals that are usually harder than other metals? alkali metals alkaline earth metals lanthanide series transition metals

The answer we’ll be c

1.I'm not Branliest but i know these answers the First one just going down the list it has finite number statement is true There are finite number of quarks which can be combined in a finite number of ways leaving a finite number of hadrons and so on.non metal elements combine are typically short electrons and will covalently bond to each other by sharing electrons so for 1. Options A and D would be true.
2. would be Transition Metals such as Iron,copper Manganese and etc have the strongest tendency so for 1 would be Option D hoped i helped  :/  

The diaphragm is what i think ur talking about

Where is the data? ? and graph
