We have to get the relationship between metallic character and atomic radius.
Metallic character increases with increase in atomic radius and decrease with decrease of atomic radius.
If electrons from outermost shell of an element can be removed easily, that atom can be considered to have more metallic character.
With increase in atomic radius, nuclear force of attraction towards outermost shell electron decreases which facilitates the release of electron.
With decrease in atomic radius, nuclear force of attraction towards outermost shell electrons increases, so electrons are hold tightly to nucleus. Hence, removal of electron from outermost shell becomes difficult making the atom less metallic in nature.
I uhhh would answer but this is actually confusing
The volume of a box with length 25 cm, height 25 cm and width 1.0 m is 0.0625m³.
Volume of the box which is a cuboid can be calculated by multiplying the length, breadth and height of the given box.
Volume of the box is given by the product of the length of the box, Height of the box and Breadth or width of the box.
Since, the box is a cuboid, hence the formula is given by the products of length, breadth and height.
Given,
length of the box= 25cm = 0.25m
Height of the box =25cm = 0.25m
width of the box= 1m
Volume = length × width × height of box
Volume = 0.25 × 0.25 × 1
Volume = 0.0625m³
The volume of the box is 0.0625m³.

C) A chlorine atom can form ionic bonds by accepting an electron and covalent bonds by sharing electrons
Explanation:
The statement that best explains the behavior of chlorine is that its atom can form ionic bonds by accepting an electron and covalent bonds by sharing electrons.
- To form an ionic bond, two atoms combines together via electrostatic attraction between them.
- Ionic bonds are formed between metals and non-metals.
- The large electronegativity difference between the two specie is the driving factor.
- In forming NaCl compound, Na donates electron which is accepted by Chlorine.
- This leaves a positive charge on Na and a negative charge on chlorine and the ensuing electrostatic attraction forms an ionic bond.
To form the covalent bond, the chlorine shares their valence electrons between themselves. They have an equal affinity for these electrons and this leads to the formation of a non-polar covalent bond

Answer:
B. It represents the change in enthalpy for the reaction.
Explanation:
The potential energy diagram for a chemical reaction shows its potential energy plotted against the reaction progress coordinate. The potential energy diagram shows how the potential energy of reactants and products vary as reactants are converted into products.
The potential energy of the system refers to energy stored in the chemical bonds of reactants and products. The difference between the potential energy of reactants and products is known as the enthalpy of reaction. This difference in potential energy may be positive or negative. A positive difference in potential energy implies an endothermic reaction while a negative difference in potential energy implies an exothermic reaction.
