Na+	1s2s2p⁶
Ca^-	1s2s2p3s3p⁶
I^-	1s2s2p3s3p3d4s3d4p5s4d6p⁶
K⁺	1s2s2p3s3p⁶
Ca²⁺	1s2s2p3s3p⁶
Br	1s2s2p3s3p4s3d4p⁶

Step by step solution

01

identifying monoatomic ions around us

the labels of several commercial products contain many monatomic ions. Six main group elements contained in the productsare,

Na⁺, Ca^-, I^-, K⁺, Ca²⁺, and Br

02

determining the electronic configuration of each

the electronic configuration of each monoatomic ion is,

Na+	1s2s2p⁶
Ca^-	1s2s2p3s3p⁶
I^-	1s2s2p3s3p3d4s3d4p5s4d6p⁶
K⁺	1s2s2p3s3p⁶
Ca²⁺	1s2s2p3s3p⁶
Br	1s2s2p3s3p4s3d4p⁶
