What is the average atomic mass of chlorine if 75.8% of chlorine atoms are 35/17 CL with a mass of 34.9589 amu and 24.2% are 37/17 CL with a mass of 36.9659 amu?

Explanation:So if a neutron or two is added or removed from the nucleus, then the ... For example Cl–35 has an atomic mass of 35 u (17 protons and 18 neutrons), while Cl–37 ... Calculate the mass contribution of chlorine–35 to the average relative atomic mass ... Which of the following are isotopes of 3517Cl? 1735Cl. 3517Cl. 3717Cl.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
