Which element results if 2protons and 2neutrons with the atomic number 88 and mass number 226? Show workings
Help please
Since this is not my area of expertise, I searched Google under the key words "atomic number 88" to get these possible sources:
http://www.wordwebonline.com/en/ATOMICNUMBER88

You could continue the search using "radium" as your key word.
I hope this helps. Thanks for asking.
To determine the element resulting from 2 protons and 2 neutrons with the atomic number 88 and mass number 226, we need to find the element with atomic number 88 on the periodic table.
Start by understanding the definitions of atomic number and mass number:
- The atomic number is the number of protons in an atom's nucleus. It determines which element the atom belongs to.
- The mass number is the total number of protons and neutrons in an atom's nucleus.
Based on this information, we know that the atomic number is given as 88, which tells us that the element belongs to the 88th position on the periodic table.
Next, consider the fact that the mass number (total protons and neutrons) is given as 226. To find the number of neutrons in the nucleus, subtract the atomic number from the mass number:
Number of neutrons = Mass number - Atomic number = 226 - 88 = 138
Now, we need to find the element with an atomic number of 88. The periodic table tells us that element 88 is radium (Ra).
Therefore, the element resulting from 2 protons and 2 neutrons with an atomic number of 88 and a mass number of 226 is radium (Ra).
Note: Google search can also provide quick answers by searching for "element atomic number 88 mass number 226."
