Which statement is true about elements in a period on the periodic table?

they have different properties that repeat across the next period.

they have different properties that show no pattern.

they have similar names.

they have similar properties.

They have different properties that repeat across the next period

Explanation:

Elements are distributed in groups and periods in a periodic table.

Elements in period are arranged in order of increasing atomic numbers, thus have different valence electrons and thus have different properties.

Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons.

Thus as the elements are arranged such that the elements with similar chemical properties occur after a regular interval, it is true that the elements in the period have different properties that repeat across the next period.

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.
