Question

Describe what happens to elements in a group as you move vertically down the periodic table? Ex. From an alkali metal in period 1 to an alkali metal in period 2.

Answer 1

As you move down the periodic table, elements in a group increase in size and atomic number.

Step-by-step explanation:

As you move vertically down the periodic table, the elements in a group generally increase in size and atomic number. This means that the alkali metal in period 2 will have more protons and electrons compared to the alkali metal in period 1. For example, lithium (Li) is an alkali metal in period 2, and it has 3 protons and 3 electrons. Sodium (Na), another alkali metal in period 3, has 11 protons and 11 electrons. This trend continues as you move down the periodic table.

Answer 2

As you move down a group, a couple of things happen:

Atomic Number, Metallic Properties, Atomic Radius, Radioactive Isotopes INCREASE

Electronegativity, Ionizaition Energy, Electron Affinity, Nonmetallic Properties DECREASE
