Periodic Table Review

Imagine Ethan, Luna, and Anika are collecting elements from the periodic table for a science project. As they move from left to right across a period to pick each element, what is the general trend of the atomic number of the elements they collect?

• Remains constant

• Fluctuates randomly

• Decreases by one

• Increases by one

Imagine Ethan, David, and William are in a science museum looking at an interactive periodic table exhibit. As they move the slider from right to left across a period, how does the metallic character of the elements change?

• The trend of metallic character decreases from right to left across a period.

• The trend of metallic character is random from right to left across a period.

• The trend of metallic character increases from right to left across a period.

• The trend of metallic character remains constant from right to left across a period.
