Question

element x,y and z have atomic number 6,9 and 12 respectively. which one a) forms anion , b) forms cation

Answer 1

anion are element y and cation are element x and z

Answer 2

Answer:

• Element Y with atomic number 9 would form an anion and element Z with atomic number 12 would form a cation.
• Cations which are “positively charged ions” and the anions which are “negatively charged ions” are formed when a nonmetal gains an electron and a metal loses an electron respectively.
• Element x with ‘atomic number’ 6 is carbon, y with 9 is fluorine, and z with 12 is magnesium.
• Magnesium is a metal so it would lose an electron to form an anion. Fluorine a nonmetal will gain an electron to form a cation.
