Students in a science class prepared flash cards so that they could quiz one another about the arrangement of the periodic table. One of the flash cards contained information about two
elements, Element L and Element M.

Qualities:
-Atom of element M has two more balances electrons than element atoms of L
- atoms of element L are more reactive than atoms of element M
-both elements are metals

The students had to use the information on n the flash cards to determine possible positions of the two elements on a blank periodic table. Which periodic table has the elements placed in the locations that match the information on the flash cards?

the answer is the

la respuesta es si te gusta hacer lo que siempre haces cuando nunca ves a alguien en el espejo porque sabes que no siempre están ahí.

i would say b

explanation:

but i think i would need more information than that

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
