This element is strontium (Sr).
atoms in the same group are similar. calcium is in group 2, so it's similar to Be, Mg, Sr, Ba and Ra. Most similar would be Mg or Sr, which are right above and below. all group 2 atoms share a similar electron configuration
Calcium is in group 2/IIA, so the other elements in that group would be expected to behave most like calcium.
Beryllium, Calcium or any other element within the same family or group (vertical column on the periodic table)
the elements that lie in the group in which magnesium lies will repeat the properties of magnesium.
The pattern between calcium and gallium is that they both belong to the same group on the periodic table, Group 2. They both have similar outer electron configurations and exhibit similar chemical properties in terms of reactivity and bonding. However, they have different atomic numbers and physical properties due to the difference in their atomic structures.
Magnesium is a metallic element with chemical properties similar to calcium.
Beryllium (Be). This is because on the periodic table Be is located in the same group (column) as Calcium and is the highest element in that column. Elements of the same group have similar properties and their masses decrease the higher they are in the group.
The element directly below calcium on the periodic table is strontium. Strontium has similar chemical properties to calcium because they belong to the same group, known as alkaline earth metals.

Calcium is an element that behaves most like magnesium due to their similar chemical properties. They are both alkaline earth metals, have similar reactivity, and form similar compounds.
Calcium is in group 2/IIA, so the other elements in that group would be expected to behave most like calcium.
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.
Calcium
The element most similar to calcium is strontium (Sr).Both calcium (Ca) and strontium (Sr) belong to Group 2 (alkaline earth metals) in the periodic table, meaning they have similar chemical properties. These similarities include:Same valence electrons: Both have two valence electrons, making their chemical behavior similar.Reactivity: Both react with water to form hydroxides and hydrogen gas.Formation of compounds: Both form similar oxides, hydroxides, and carbonates.Ionic radius and bonding: Strontium’s ionic radius is slightly larger than calcium’s, but they can often substitute for each other in minerals.Another similar element is magnesium (Mg), which is directly above calcium in the periodic table and shares many chemical and biological functions. However, strontium is even more chemically similar due to its closer atomic size and properties.
Strontium and barium are two elements that have similar properties to calcium because they belong to the same group in the periodic table (group 2 alkaline earth metals) and exhibit similar chemical behavior due to having the same number of valence electrons.
the elements that lie in the group in which magnesium lies will repeat the properties of magnesium.
