Question

A. A main group element with the valence electron configuration 2s¹ is in periodic group .
It forms a monatomic ion with a charge of .
B. A main group element with the valence electron configuration 2s²2p⁵ is in periodic group .
It forms a monatomic ion with a charge of .

Enter the type of subshell affected by the gain or loss of electrons. DO NOT enter the specific subshell. For example: If electrons are added to the 3p subshell, enter p. If electrons are lost from the 4s and 3d subshells, enter s + d.

A. An element with the valence electron configuration 2s¹ would form a monatomic ion with a charge of .
In order to form this ion, the element will  (lose/gain) electron(s) from/into the subshell(s).

B. If an element with the valence configuration 4s¹3d⁵ loses 2 electron(s), these electron(s) would be removed from thesubshell(s).

B. An element with the valence electron configuration 2s²2p⁴ would form a monatomic ion with a charge of .
In order to form this ion, the element will  (lose/gain) electron(s) from/into the subshell(s).

Answer 1

A. A main group element with the valence electron configuration 2s¹ is in periodic group-1 .
It forms a monatomic ion with a charge of +1
B. A main group element with the valence electron configuration 2s²2p⁵ is in periodic group-17 .
It forms a monatomic ion with a charge of -1

A. An element with the valence electron configuration 2s¹ would form a monatomic ion with a charge of +1
In order to form this ion, the element will  lose electron(s) from thesubshell 2s.

B. If an element with the valence configuration 4s¹3d⁵ loses 2 electron(s), these electron(s) would be removed from the subshells 4s and 3d.

A. An element with the valence electron configuration 2s¹ would form a monatomic ion with a charge of +1
In order to form this ion, the element will  lose electron from the subshell 2s
B. An element with the valence electron configuration 2s²2p⁴ would form a monatomic ion with a charge of -2
In order to form this ion, the element will  gain electrons into thesubshell 2p
