If an element is the last element in its period, it means that element has the highest atomic number and electron capacity in that period. It typically signifies a transition to the next period, where chemical properties may change due to different electron configurations.
i dont know i was waiting for u to tell me.....
Hydrogen is found in every acid. Acids are compounds that release hydrogen ions (H+) in solution.
Every single atom of sodium has exactly 11 protons in the nucleus.
its the 4th period

The number of electrons in its valence shell

Every element, organism, and creature that God made shares a common characteristic of being a part of His creation, reflecting His creativity and design.
Helium is a period 1 element.
Hydrogen is found in every acid. Acids are compounds that release hydrogen ions (H+) in solution.
Every single atom of sodium has exactly 11 protons in the nucleus.
He is in period 1.
That is not true. The first element in a period may be active or inactive, depending on the specific electron configuration of the element. For example, the first element in period 1, hydrogen, is not considered an active element.
The element neon is in period 2. Classified as a non-metal. :)
The element in period 4 with the highest electronegativity is chlorine.
