How many of the following given atomic number have noble gas configuration? 56, 57, 70, 80, 24

The correct answer is 0.

To determine how many of the given atomic numbers have a noble gas configuration, we first need to identify the atomic numbers of the noble gases in the periodic table. Noble gases belong to Group 18 of the periodic table and are characterized by having completely filled valence electron shells, making them highly stable.

The atomic numbers of the noble gases are:
- Helium (He): 2
- Neon (Ne): 10
- Argon (Ar): 18
- Krypton (Kr): 36
- Xenon (Xe): 54
- Radon (Rn): 86
- Oganesson (Og): 118

Let's compare the given atomic numbers to this list of noble gas atomic numbers:
- 56: This is Barium (Ba), an alkaline earth metal (noble gas is Xe with atomic number 54).
- 57: This is Lanthanum (La), a transition metal/lanthanide.
- 70: This is Ytterbium (Yb), a lanthanide.
- 80: This is Mercury (Hg), a transition metal.
- 24: This is Chromium (Cr), a transition metal.

Comparing the list of given atomic numbers (56, 57, 70, 80, 24) against the atomic numbers of the noble gases (2, 10, 18, 36, 54, 86, 118), we find that none of the given atomic numbers match any noble gas.

Therefore, the number of given atomic numbers that have a noble gas configuration is 0.
