QUESTION:

Indicate if the atoms in each pair have the same number of protons, neutrons, and electrons. (3.4)a. 3717 Cl, 3818Arb. 3614Si, 3514Sic. 4018Ar, 3917Cl

ANSWER:

Solution 85 UTCHere we have to indicate if the atoms in each pair have the same number of protons, neutrons, and electrons. Step-1a. 3717 Cl, 3818 ArIt is known that for neutral atom the atomic number (Z) = number of proton (P) = number of electron (e) Thus for Cl the number of electron = number of proton = 17Number of neutron of Cl = 37-17 = 20For Ar the number of electron = number of proton = 18N
