How to Write Proper Chemical Designations for Isotopes?

[kingbryant]

Homework Statement

write the "proper chemical designation" for the following isotopes
a. uranium-238
b. carbon-14
c.polonium-210

Homework Equations

The Attempt at a Solution

would i just state number of protons, electrons and neutrons
uranium-238 carbon-14 polonium-210
p-92 p-6 p-84
e-92 e-6 e-84
n- 238-92=146 n 14-6=8 n-210-84=126

IS THIS HOW TO SHOW "PROPER CHEMICAL DESIGNATION" OR IS THERE A DIFFERENT WAY

Err, you want the chemistry section.

TO REPRESENT IT?

The proper chemical designation for an isotope includes the element symbol, mass number, and atomic number. For example:

a. Uranium-238 would be written as 238U or U-238, where 238 is the mass number and U is the element symbol for uranium with atomic number 92.

b. Carbon-14 would be written as 14C or C-14, where 14 is the mass number and C is the element symbol for carbon with atomic number 6.

c. Polonium-210 would be written as 210Po or Po-210, where 210 is the mass number and Po is the element symbol for polonium with atomic number 84.

So, the proper chemical designations for the given isotopes are:

a. 238U or U-238
b. 14C or C-14
c. 210Po or Po-210
