Question

An element X contains 15 number of protons. X gains three electrons and forms an ion. Identify the element. Write the way how you will symbolise the ion and find the number of electrons and protons present in the ion formed. ​

Answer 1

Answer:

If the atomic number of an element X is 13.The number of electrons in its ion x3+  will be 10. This is because x3+ is a positively charged cation. An atom loses electrons from its valence shell and becomes positively charged ion called cation. Here, Atom X loses 3 electrons and acquires 3+ charge. therefore the number of electrons lost will be 3. and the number of electrons in its ion x  3+   will be 10.
