Which of the following is correct regarding Electropositive character of alkali earth metals?

What is meant by diagonal relationship in periodic table?
A Diagonal Relationship is said to exist between certain pairs of diagonally adjacent elements in the second and third periods of the periodic table. On crossing a period of the periodic table, the size of the atoms decreases, and on descending a group the size of the atoms increases.
What is the cause of diagonal relationship in periodic table?
Diagonal relationship is formed due to the identical size of ions. As we move towards right across a period in the periodic table, then the size of the atom reduces, and when we move downward across a group then the size of the atoms gradually increases.
What is diagonal effect?
What is the Diagonal Effect? – Elements have the tendency to not have characteristics of their own family, but characteristics close to the element that is right one and down one, hence the word diagonal.
What is the reason behind diagonal relationship?
Diagonal relationships occur because of the different ways in which many atomic properties vary down groups and across periods of the Periodic Table. In addition to the group and period relationships, the elements of s and p-block elements also exhibit diagonal relationships.
Why diagonal relationship is shown in second and third period elements?
The diagonal relationship is shown by 2nd and 3rd-period elements of the periodic table as they have similar properties. The diagonal relationship is due to similar sizes of atoms or ions and electronegativities of the participating elements and the same polarising power.
Does oxygen and chlorine show diagonal relationship?
Answer: So answering your question : Yes , oxygen and chlorine do show diagonal relationship. …
What is diagonal relationship What are the main reasons for the anomalous Behaviour of the elements belonging to the second periods?
Reasons for Anomalous Periodic Properties Small size of these atoms. High electronegativity. Large charge/radius ratio.
What are anomalous Behaviour of second period elements?
Thus bonding in the second-period elements is restricted to form 4 bonds. Thus anomalous behavior of any group second period element is due to small size, large charge/radius ratio, and high electronegativity of the elements, and covalence cannot exceed four.
What are second period elements?
The second period contains the elements lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
