The correct answer is polarizing power increase.
The polarizing power of these ions grows as they move through a period because their charge increases and their size decreases. The size grows and the polarizing strength reduces as one descends a group. These two effects somewhat cancel each other out while travelling diagonally, preventing a noticeable change in attributes. As a result, the attributes of these diagonally oriented elements behave similarly.
What is polarizing power?
The capacity of a cation to distort an anion is known as its polarization power. The term "polarizability" refers to an anion's propensity to get polarized by a cation. The charge and radius of a cation affect its ability to polarize. The relationship between charge and radius and cation polarization power. Because they are directly proportional to one another, polarization power of the cation increases as cation charge increases.

Answer:
C- A proton has about the same mass as a neutron .
Explanation:
In an atom such as a carbon atom, the masses of the proton and neutrons are the same.
The mass of the electrons is very negligible.
- Protons are the positively charged particles in an atom
- Neutrons do not carry any charges
- Both protons and neutrons have similar masses.
- They contribute the bulk of the mass of the atom.
- The electrons carry negative charges and they have negligible masses.
The mass of protons and neutrons are similar.
Answer:
The higher the vapor pressure of a liquid at a given temperature, the lower the normal boiling point of the liquid.
Explanation:
Recall that a mole is defined as Avogadro's number of particles what the formula of caffeine basically tells us is that every molecule of caffeine you will have 8 atoms of carbon 10 atoms of hydrogen 4 atoms of nitrogen and 2 atoms of oxygen so if we have 0.3 moles of caffeine we will have 4*0.3 moles of nitrogen which is 0.12 and you got the idea
