Question

How does the reactivity of neonatonic number 10. 2 group 18 defer from that sodium atomic number 11. Three group one explain the reasoning based on the properties of neon sodium that you can infer based on their atomic numbers. In groups in two sentences

Answer 1

Neon (atomic number 10), a noble gas in group 18, is very unreactive due to its complete outer electron shell, which makes it stable and unlikely to form chemical bonds. In contrast, sodium (atomic number 11), an alkali metal in group 1, is highly reactive because it has one electron in its outer shell that it readily loses to achieve stability, resulting in strong reactivity with other elements.
