Moving from the element

with atomic number 10 to
atomic number 11 on the
periodic table, there is a
change in reactivity. What is
the change that is found in
the reactivity? (1 point)
Element 10 will
easily combine with
element 11
Noble gases are
inert. Alkali metals
are very reactive.
Noble gases are
very reactive. Alkali
metals do not react.
Neither element is
very reactive at all.

When moving from element 10 (neon, a noble gas) to element 11 (sodium, an alkali metal) on the periodic table, the change in reactivity is that element 10 (neon) is inert and does not readily react with other elements, while element 11 (sodium) is very reactive. Therefore, the correct interpretation of the change in reactivity is:

Noble gases are inert. Alkali metals are very reactive.

If you are required to choose from the options, the appropriate statement would be:

Noble gases are inert. Alkali metals are very reactive.
