Question

Symbol of the element with atomic number = 30, mașs number 65 is a) Sn b) Zn c) Mn d) N​

Answer 1

Answer:

option B

zinc is the answer for your question

Answer 2

The correct answer is Zn (Zinc) ( Option B).

• The Atomic number of an element is defined as the number of protons present in the element.
• The elements in the periodic table are assigned in the increasing order of the number of protons.
• The number of protons of an element = the atomic number of an element.
• The atomic number is also denoted by Z. The atomic mass of a number is denoted by A.

• The element with atomic mass 65 and atomic number 30 is Zinc which is symbolically represented as Zn.
• The atomic number of Manganese(Mn) is 25 and its atomic weight is 55.
• The atomic number of Tin is 50. It is represented by the symbol Sn. Its atomic mass is 118.7.
• The atomic number of Nitrogen is 7. It is denoted by the symbol N. Its atomic mass is 14.

Therefore, the element with atomic number 30 and mass number 65 is Zn. Option B is the correct answer.
