Question

complete the missing information. the first one is completed as an example. atomic structure: protons, neutrons, electrons; atomic calculations: atomic # = #p, #p = #e, mass # = #p + #n; identity: determine the atomic number and identify the atom by using the periodic table.; isotope: symbol - mass; isotope notation: mass#p x; #protons = 3, atomic # = 3, #electrons = 3, #neutrons = 4, mass # = 7, li, lithium, li - 7, 73li; #protons = _, atomic # = _, #electrons = 9, #neutrons = _, mass # = _, f - 19

Explanation:

Step1: Recall proton - electron relationship

In a neutral atom, the number of protons (#P) is equal to the number of electrons (#e). Given #e = 9, so #P=9.

Step2: Determine atomic number

The atomic number is equal to the number of protons. So atomic number = 9.

Step3: Calculate number of neutrons

The mass number of F - 19 is 19. Using the formula Mass # = #P+#N, and since #P = 9, then #N=Mass # - #P = 19 - 9=10.

Step4: Determine mass number

The isotope is F - 19, so the mass number is 19.

Answer:

#Protons = 9
Atomic # = 9
#neutrons = 10
Mass # = 19
