What elements atomic numbers add up to 200

What elements atomic numbers add up to 200?

The Correct Answer and Explanation is :

To find elements whose atomic numbers add up to 200, we can start by identifying a few atomic numbers of known elements. The atomic number is the number of protons in an atom’s nucleus, and it uniquely identifies each element.

Here’s one way to combine atomic numbers to achieve a total of 200:

1. Carbon (C) – Atomic number 6
2. Iron (Fe) – Atomic number 26
3. Silver (Ag) – Atomic number 47
4. Osmium (Os) – Atomic number 76

Now, let’s calculate the sum of these atomic numbers:

• Carbon (6) + Iron (26) + Silver (47) + Osmium (76) = 155

This combination doesn’t achieve the desired total, so we need to adjust our selections. Here’s a correct combination:

1. Calcium (Ca) – Atomic number 20
2. Titanium (Ti) – Atomic number 22
3. Platinum (Pt) – Atomic number 78
4. Gold (Au) – Atomic number 79

Calculating this combination gives:

• Calcium (20) + Titanium (22) + Platinum (78) + Gold (79) = 199

However, we can add Bismuth (Bi), which has an atomic number of 83, resulting in a total of 200:

1. Calcium (Ca) – 20
2. Titanium (Ti) – 22
3. Platinum (Pt) – 78
4. Gold (Au) – 79
5. Bismuth (Bi) – 83

Another possible set might include:

1. Neon (Ne) – Atomic number 10
2. Argon (Ar) – Atomic number 18
3. Tin (Sn) – Atomic number 50
4. Zirconium (Zr) – Atomic number 40
5. Lead (Pb) – Atomic number 82

These selections showcase how a diverse range of elements can combine their atomic numbers to reach a sum of 200. The study of atomic numbers not only helps in understanding elements but also their properties and how they interact in various chemical reactions.
