List the number of protons neutrons and electrons in 13/6 C
Charra [1.4K]
<h3>Answer:</h3>

             Number of Protons =  6

             Number of Electrons  =  6

             Number of Neutrons  =  7

<h3>Explanation:</h3>

Number of Protons:

                               As the number of protons present in the nucleus are equal to the atomic number therefore, using periodic table one can easily find out the atomic number of C atom. Hence, C is present in group 14 and period 2 and having an atomic number of 6. Therefore, number of protons in C atom are 6.

Number of Electrons:

                                 As shown in statement, C is not carrying any type of charge. It means this atom is neutral in nature. Which means, it is carrying the same number of electrons as the number of protons in order to give a neutral atom. Therefore, it contains 6 electrons.

Number of Neutrons:

                                  Number of neutrons can be calculated using following formula,

                  No. of Neutrons  =  Atomic Mass - Number of Protons

As,

                                    Atomic Mass  =  13

So,

                                    No. of Neutrons  =  13 - 6

                                    No. of Neutrons  =  7

Hydrogen gas is collected by downward displacement of water why​
77julia77 [94]

Explanation:

Hydrogen is collected by downward displacement of water as it is less denser than water. Hence it comes out at the surface of water . It is insoluble in water so it does not dissolve in water. ... So, it is impossible to collect hydrogen gas in air medium.22-O
