Write the proper charges so that an alkali metal, a noble gas and a halogen have the same electron configurations. what is the # of protons in each? # of electrons in each? how many filled energy levels do each have? arrange them from smallest to largest ie & explain. arrange from smallest to largest radii and explain.

Explanation:

1) Sodium is an alkali metal which positive sodium ion after losing an electron.

After losing an electron it will attain stable electronic configuration.

Number of protons in sodium ion  = 11 protons

All filled energy levels in Sodium ion

2) Neon is noble gas with fully filled outermost valence shell. Inert in nature

Number of protons in neon atom = 10 protons

All filled energy levels in Neon atom

3) Fluorine belongs to halogen family. Highly electro-negative element. By gaining one electron it will attain attain form negatively charged ion

.

By gaining one electron it will attain stable electronic configuration.

.

Number of protons in fluorine ion = 9 protons

All filled energy levels in fluorine ion

All these ions are isoelectronic species with different number of protons and same number of electrons.

answer: i would say b.

explanation:

the dissolution of polymer can be thermodynamically described in 2 steps.
