Respuesta :
The correct answer would be the last option. Β The property that is common to all group 2 elements is that they Β tend to form ionic bonds by losing electrons making these atoms positive charge. They are called cations. These elements are beryllium, magnesium, calcium, strontium, and radium.Β
Answer: Option (d) is the correct answer.
Explanation:
Group 2 elements are also known as alkaline earth metals and they are rich in electrons.
For example, calcium is a group 2 element with atomic number 20 and its electronic configuration is 2, 8, 2. In order to gain stability, calcium loses to electrons and becomes [tex]Ca^{2+}[/tex] ion.
Similarly, all the elements of group 2 donates electrons in order to form ionic bonds.
Hence, we can conclude that all group 2 elements have in common that they tend to form ionic bonds by losing electrons.
