Answer:
Protons
Explanation:
The atomic number represents the number of protons. Therefore, as the atomic number increases, the number of protons does too.
I hope this helps! :)
D. this is the correct answer because the question is showing a comparison of sizes rather than the actual sizes which eliminates B. A and C have no relevance.
Molarity = Moles/Liter
Use the molecular atomic mass of NaCl to convert from grams to moles.
Molecular mass of NaCl is the sum of its atomic masses. Look at the periodic table to find these. Na is 23 g/mol and Cl is 35.5 g/mol ,
so NaCl = 23 + 35.5 = 58.5 g/mol
multiply to cancel out grams
76 g NaCl * (1mol / 58.5 g NaCl) = 1.3 mol NaCl
over 1 Liter is just 1.3 M NaCl
Hope this helps!
Ch = sh = why and find the stuff
1 and 3 only because metal are easily to loss electron while non metal are difficult to loss electron that's why it called heavy elements.
