Question

The atom with atomic number 12 will most likely combine chemically with the atom whose atomic number is

• A. 3
• B. 10
• C. 11
• D. 16

Answer 1

The correct option is D 16

The distribution of electron shell for atomic number 12 will be 2,8,2. So this element can lose its 2 electron in valence shell to attain a noble gas configuration. This element will combine with other element which gain this 2 electrons and attain a noble gas configuration. Hence element with atomic number 16 has 2,8,6 electron arrangement, it will gain the two electron to attain stable noble gas configuration of 2,8,8. Thus atom with atomic number 12 will most likely combine chemically with atom of atomic number 16.
