Psychrometer is an instrument used to measure atmospheric humidity.It consist of two thermometer that is wet bulb thermometer and dry bulb thermometer.
Match each weather instrument with its description.
An atom of sodium, with an atomic number of 11, has 11 protons and 11 electrons. The atomic number is indicative of both the number of protons in an atom and, in a neutral atom, the number of electrons.
The atomic number of an element corresponds to the number of protons in the nucleus of its atom. So, an atom of sodium whose atomic number is 11 has 11 protons. As the atom is neutral, it also means that the atom will have 11 electrons to balance the 11 positive charges of the protons. This information can be found on the periodic table, which gives the atomic number and the atomic mass of each element.

Answer:
Molecular bonding cannot occur without electrons.
Explanation:
In order to be 100% correct, the answers should be electrons, protons and neutrons. Since moleculas are formed by atoms and atoms are formed by electrons protons and neutrons.
However, if we consider only the bonding itself, the most important atomic particle is the electron. Molecular or convalent bonding happens when atoms share electrons pairs to reach stability.
Explanation:
Matter in which molecules have strong force of attraction are held tight together. Therefore, to break this force of attraction strong force is required.
This type of matter is know as solid. Also, it is known that solid substances have definite shape and volume.
Thus, we can conclude that a substance with a definite shape and volume is a solid phase of matter.
