Answer:
No element shares the same atomic number. The atomic number of every element is unique to itself, just like a fingerprint is unique to a human. The atomic number of element allows us to identify it, like how we can identify a person from their fingerprint.
Explanation:
The solvent, solute, and solution.
Answer:2. 109 g NaCl
3. 31.9 g ZnCl2
4. 15.4 g Al2O3
Explanation: First find moles of the given compound
Next do the mole ratio between both compounds
Convert moles to mass.
Pt195 having 78 atomic number is the daughter nucleus produced when Au195 undergoes electron capture.
An unstable isotopes can undergoes radioactive decay to form a more stable isotopes . Initial isotopes is called parent nuclide and the resultant isotopes from radioactive decay is called the daughter nuclide There are several radioactive decay like alpha decay , beta decay , gamma decay , electron capture etc .
In electron capture , the atom have only one less which is daughter isotopes than electron than atomic number of parent isotopes.
