Question

atomic numbers for atoms blank in increments of blank as you move across the periodic table

Answer 1

The atomic numbers of atoms increase sequentially as you move across the periodic table from left to right. Specifically, the atomic number increases by 1 for each successive element. For example, the element hydrogen (H) has an atomic number of 1, helium (He) has an atomic number of 2, lithium (Li) has an atomic number of 3, and so on.

To summarize:
- Atomic numbers increase by **1** as you move across the periodic table.
