There are various kind of elements that are present in periodic table. Some elements are harmful, some are radioactive, some are noble gases. The atomic radius in decreasing order is Bi>Sb>As>N>O.
<h3>
What is periodic table?</h3>
Periodic table is a table in which we find elements with properties like metals, non metals, metalloids and radioactive element arranges in increasing atomic number.
Along the period, the size of elements decreases. Down the group the size of elements increases. The atomic radius in decreasing order is Bi>Sb>As>N>O.
Therefore, atomic radius in decreasing order is Bi>Sb>As>N>O.

The attraction mediated flow of water in the narrow tube has been termed as Capillary action. Thus, option A is correct.
The process of flowing up of liquid with the attraction force between the molecules and the surface has been achieved with the surface characteristics.
<h3>Movement of water in a narrow tube</h3>
The surface has the force of attraction with the flowing liquids in the sample. It results in the increased surface interaction, and the liquid flows up in the tube against gravity.
The movement of the liquid in the water through a narrow tube has been termed as capillary action. Thus, option A is correct.

Hydrogen and oxygen cn form a polar covalent bond
They have the same density because a material, no matter how much of it there is, will always be a certain density. A 40g ball of iron has the same density as a 1g ball of iron.
ion, proton
Explanation:
Ions and protons have profound relationships.
An ion is an atom that has lost or gained electrons.
A proton is a positively charged subatomic particle.
What is the relationship between an ion and a proton?
- In an atom, there are three fundamental particles.
- Protons are the positively charged particles located in the nucleus of atoms.
- Electrons are the negatively charged particles orbiting round an atom.
- Neutrons have no charges and they occupy the nucleus with protons.
Atoms are electrically neutral and this implies that they have equal number of protons and electrons.
In an ion, the number of protons and electrons differ.
For positive charged ions, the number of protons is more suggesting they have lost electrons.
For negatively charged ions. the number of protons is less suggesting they must have added electrons.
Compound are combinations of different atoms.
