Secure https://session.masteringchemistry.co February 15 Pre-Class Assessment Question for Group Work 4.121 Constants | Periodic Tabl Complete the following table. In the #in #in Charge nucleus? 3K 81Br (yes/no) atom ion Particle (amu) Proton Neutron ElectronExplanation / Answer
1939K
atomic number of potassium is 19 .So number of protons and electrons are equal to 19 in neutral atom. No of neutrons are equal to n = A-Z ( A is atomic mass, Z is atomic number)
K is neutral atoms . so it has 0 charge
particles mass charge in the nucleus
protons = 19 39.093amu 0 yes
electrons = 19
neutrons = 39-19 = 20
3581Br^-
Br + e^- ----------------> Br^-
35e^- 36e^-
35P 35P
Br^- has -1 charge
very atom contains nucleus .
particles mass charge in nucleus
protons = 35 81 -1 yes
electrons = 36
neutrons = 81-35 = 46
