PLEASE HELP ME I DONT WANT TO FAIL to answer this periodic table you got to read the bottom clues to fill in the boxes on top the elements are represented in the real s and p block in the periodic table

Within each element square, information on the element's symbol, atomic number, atomic mass, electronegativity, electron configuration, and valence numbers can be found. At the bottom of the periodic table is a two row block of elements that contain the lanthanoids and actinides.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
