Answer:
Iodine have higher atomic size than tellurium because of the presence of more number of protons and lower atomic mass than tellurium because of the presence of lower number of neutrons.
Explanation:
Atomic number of an element is the number of the protons present in the element.
Atomic mass is the sum of a protons and the neutrons which are present in the nucleus of the atom.
Iodine has higher atomic number than tellurium because it has more number of protons than the tellurium.
On the other hand, iodine has lower atomic mass than tellurium because it has less number of neutrons in its core.
Liquid silver is less dense than solid silver, so the solid silver would sink
A reaction in which bonds are created is usually associated with the Release of energy.
What are the various types of bonds?
There are three sorts of bonds:
1. Electrovalent or electrovalent bond
2. chemical bond
3. dative bond
Electrovalent or electrovalent bond are formed when one or more electrons are transferred from one atom to another.
Covalent bonds are formed when the atoms during a molecule share an equal number of electrons.
A dative bond is one in which both electrons in a shared pair come from the same atom.
Now, atoms tend to stabilize once they form chemical bonds, releasing energy within the process. Energy is released because there's a higher level of stability associated with a low energy level.
Hence, a reaction in which bonds are created is usually associated with the release of energy.
