what group and period is sodium in?

• Group 3 period 1

• group 3 period 3

• group 1 period 3

• group 3 period 3

What answer best describes the reason for patterns in reactivity for group 1 Alkali metals?

• As we go down the group more shells take the outer electron futher from the nucleaus so the force holding it in place is weaker

• As we go down the group less shells bring the outer electron closer to the nucleaus so the force holding it in place is stronger

• As we go down the group more shells take the outer shell futher from the nucleaus so the force pulling in the 8th electron is weaker

• As we go down the group less shells bring the outer shell closer to the nucleaus so the force pulling in the 8th electron is stronger

What answer best describes the reason for patterns in reactivity for group 7 Halogens?

• As we go down the group more shells take the outer electron futher from the nucleaus so the force holding it in place is weaker

• As we go down the group less shells bring the outer electron closer to the nucleaus so the force holding it in place is stronger

• As we go up the group more shells take the outer shell futher from the nucleaus so the force pulling in the 8th electron is weaker

• As we go up the group less shells bring the outer shell closer to the nucleaus so the force pulling in the 8th electron is stronger
