Q. 6.148 - An Introduction to General, Organic, and Biological Chemistry

Question

Complete the following table for atoms or ions: $(6.1)$

Step-by-Step Solution

Answer

Atom or Ion	Number of protons	Number of electron	Electron loss/ Gained
${\mathrm{Zn}}^{2+}$	${30}^{+}$p	$28 e^{-}$	$2 e^{-}$lost
$\mathrm{Kr}$	${36}^{+}$p	$36 e^{-}$	0
${\mathrm{S}}^{2-}$	${16}^{+}$p	$18 e^{-}$	$2e^{-}$ gained
${\mathrm{Sn}}^{4+}$	${50}^{+}$p	$46 e^{-}$	$4e^{-}$ lost

Step 1: Given Information

We need to complete the table.

Step 2: Simplify

Atom or Ion	Number of protons	Number of electron	Electron loss/ Gained
$Z{n}^{2+}$	${30}^{+}p$	$28e^{-}$	$2e^{-} lost$
$\mathrm{Kr}$	${36}^{+}p$	$36e^{-}$	$0$
${\mathrm{S}}^{2-}$	${16}^{+}p$	$18e^{-}$	$2e^{-} gained$
$S{n}^{4+}$	${50}^{+}p$	$46e^{-}$	$4e^{-} lost$
