Question

jailah needs a replacement for lithium for a science experiment. she tries silicon, but it does not work. using what you know about patterns in the periodic table, which advice would you give jailah?
a. try a lanthanide series element
b. try a non - metal from the halogen group
c. try an element in the same group as lithium
d. try an element in the same period as lithium

Explanation:

Elements in the same group of the periodic table have similar chemical properties. Lithium is an alkali - metal. To find a replacement for lithium, an element in the same group as lithium would be a good choice as they share similar reactivity and other chemical characteristics. Lanthanide series elements have different properties. Halogens are non - metals with very different properties from lithium. Elements in the same period as lithium have different chemical behaviors compared to lithium.

Answer:

C. Try an element in the same group as lithium
