Question

what information do you get from each element on the periodic table? what does it mean if elements are in the same group? what does it mean if elements are in the same period? carbon 12.011 6

Explanation:

1. From the periodic - table entry of carbon: The number 6 is the atomic number, which means carbon has 6 protons. The number 12.011 is the atomic mass, an average of the masses of its isotopes.
2. Elements in the same group have the same number of valence electrons, which gives them similar chemical properties.
3. Elements in the same period have the same number of electron - energy levels.

Answer:

• Information from carbon's periodic - table entry: Atomic number (6, number of protons), atomic mass (12.011).
• Elements in the same group: Same number of valence electrons, similar chemical properties.
• Elements in the same period: Same number of electron - energy levels.
