An element x two shells and has 6 electron in its valency shell and another element y has three shells and three electronic its valence shell write the electronic configuration of x and y show the formation of their ions write the formula of the compound formed by the combustion of these ions
Answers
Answer:
(a) two shells, both of which are completely filled with electrons: Only noble gas elements has completely filled orbitals. Neon(10)=2,8 has two shells, both of which are completely filled with electrons.
(b) The element with electronic configuration 2,8,2 has atomic number =12. The element is Mg Magnesium.
(c) A total of three shells, with four electrons in its valence shell. The electronic configuration is =2,8,4. Atomic number=14. Element is Si Silicon.
(d) A total of two shells, with three electrons in its valence shell. electronic configuration is =2,3 Atomic number =5. The element is B Boron.
(e) Twice as many electrons in its second shell as in its first shell. The first shell can have maximum 2 electrons. Therefore the electrons in second shell =4. Atomic number is =6. The element is C Carbon.
