Atomic Number of Elements in Periodic Table. We remember from our school chemistry course that every element has its own specific atomic number. It is the same as the number of protons that the atom of each element has, so sometimes atomic number is called proton number. It is always the whole number and it ranges from 1 to 118, according to. List of Elements in Atomic Number Order¶. The names and symbols for elements 112-118 are under review. The temporary system recommended by J Chatt, Pure Appl. Chem., 51, 381-384 (1979) is used above.
An element has an atomic number of 76. What is the number of protons and electrons in a neutral atom of the element?
1 Answer
The number of (i) protons and (ii) electrons, are each
Explanation:
By definition, the atomic number,
Atomic Number 76 Mass Number 192
And if there are 76 positively charged particles, there must also be 76 negatively charged particles, 76 electrons, associated with the atom.
