Question

sep use models when and if element 119 is discovered, predict where it would be placed on the modern periodic table. explain your reasoning.

Explanation:

The modern periodic table is organized by atomic number. The last element in period 7 is oganesson (atomic number 118). Since element 119 has an atomic number one more than 118, it would start a new period (period 8). Group 1 elements have 1 valence electron. The electron configuration of element 119 would likely end with a single electron in the 8s orbital (similar to how group 1 elements have their outermost electron in an s - orbital), so it would be in group 1.

Answer:

Element 119 would be placed in period 8, group 1 of the modern periodic table.
