Looking at the elements 10

Question

and 11 on the periodic table,
what can you tell me about
the size of the atom as you
go from 10 to 11? (1 point)
Going from 10 to 11
the atom size is
larger, so it is less
reactive
Going from 10 to 11

Answer 1

Element 10 on the periodic table is neon (Ne), and element 11 is sodium (Na). As you move from neon to sodium, the atomic size increases because sodium is further down the periodic table, meaning it has more electron shells than neon.

Regarding reactivity, sodium is much more reactive than neon due to its larger atomic size and the presence of a single electron in its outermost shell, which it tends to lose easily. In contrast, neon is a noble gas with a complete valence shell, making it very stable and unreactive.

Therefore, the correct statement is:

Going from 10 to 11 the atom size is larger, so it is more reactive.
