Question

किसी तत्व का परमाणु क्रमांक 27 एवं उसके परमाणु में इलेक्ट्रॉन की संख्या 14 एक इलेक्ट्रॉन की संख्या होगी​

Answer 1

Answer:

Solution :

Given that, charge = + 3, mass number = 27 and number of neutrons = 14 <br> Number of protons = atomic number <br> Atomic number = mass number - number of neutrons = 27-14 = 13 <br> This is the atomic number of aluminium. <br> Therefore, this element is aluminium. <br> Therefore, this element is aluminium (Al). <br> Number of electrons in the Al atom = 13 <br> Number of electrons in the

ion = 13-3 = 10. <br> As it is formed from the neutral atom by loss of 3 electrons.
