gain an electron to form a -1 anion and could form an ionic bond with a metal

gain an electron to form a -1 anion and could form an ionic bond with a non-metal

Identify the transition metal ion and the number of electrons with the following electron configuration, [Ar]4s03d7

How many electrons are in an ion formed from an atom located in group 6A and period 3?

loss an electron to form a -1 anion and could form an ionic bond with a metal

gain an electron to form a -1 anion and could form an ionic bond with a metal

gain an electron to form a -1 anion and could form an ionic bond with a non-metal

Explanation / Answer

1) 3rd shell comprises of 3s, 3p and 3d subshell. s-subshell has one orbital, p subshell has 3 orbitals and d-subshell has 5 orbitals.Thus there are a total of 9 orbitals in 3rd shell

2) None of the atoms can have 7 electrons in their p-subshell.Thus, the given electronic configuration is wrong.

3) The correct option is :- gain an electron to form a -1 anion and could form an ionic bond with a metal

4) None of the atoms can have 3 electrons in their s-subshell.Thus, the given electronic configuration is wrong.

5) The atyom is sulfur and the ion formed is S2-.Thus, the number of electrons are 18
