Emilio wants to tell a friend where an element's name is located within it's box in the periodic table. Which of the following is an accurate explanation to find an element's name? the name is at the top of the box

the name is the large letter or letter combination in the box

the name is the word below the large letter combination in the box

the name is the last piece of information in the box

The name is the word below the large letter combination in the box

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7

cu2o

i think tornado but not 100%
