Barium has more energy levels. So it has lesser ionization energy.
Beryllium, Calcium or any other element within the same family or group (vertical column on the periodic table)
Actinides
Element family number 2, known as the alkaline earth metals, includes the elements beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). These elements share similar chemical properties, such as forming 2+ cations and being reactive.

The element symbol for barium is Ba.
Beryllium, Calcium or any other element within the same family or group (vertical column on the periodic table)
All you have to do is look at which group Beryllium is in and look at the other elements that are in the same column. The gruop of an element can help you determine its chemical properties. That group would be Group 2 with Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.
Ba, because it is lower on the periodic table
Actinides
Barium has a larger atomic radius than beryllium. This is because as you move down a group on the periodic table, the atomic radius tends to increase due to the addition of energy levels. Barium is located lower in the periodic table than beryllium, leading to a larger atomic radius.
Calcium is a member of group 2, whose elements are beryllium, magnesium, calcium, strontium, barium and the radioactive radium.
Beryllium chloride has more covalent character than barium chloride because beryllium is a smaller cation with a higher charge density, leading to stronger interactions with the chloride anions. This results in a more polar covalent bond in beryllium chloride compared to the more ionic bond in barium chloride due to the larger size and lower charge density of barium.
Beryllium, magnesium, calcium, strontium, barium, and radium.
Element M can be a choice of 4 elements, Beryllium, Magnesium, Calcium, or Strontium. The element must have an oxidation of +2, which means group 2 elements. The atomic radius of a barium atom is 222pm. Radium has a larger atomic radius that Barium, so that is eliminated, and Barium is the same as Barium so that is also eliminated.
Six elements are there. And they are: beryllium, magnesium, calcium, strontium, barium, radium
Beryllium, Magnesium, Calcium, Strontium, Barium and Radium
Group 2 elements or alkaline earth metals are beryllium, magnesium, calcium, strontium, barium and radium
