Concept explainers
Interpretation:
The similar and different about the valence electrons of the elements in a group should be determined.
Concept introduction:
Periodic Table contains periods and groups. There are 18 groups and 7 periods in the periodic table. The vertical columns are known as groups and horizontal rows are known as periods.
The numbering of periods is done as 1 to 7 from top to bottom and groups are named as 1A, 2A, 3B to 8B, 1B, 2B, 3A to 8A from left to right where A represents representative elements and B represents

True or False?arrow_forwardDescribe atomic structure; name and describe the parts of atoms, and their arrangement/location and chargearrow_forwardWhich of the following elements would have chemical properties similar to Ca K, Ba, Kr, or Scarrow_forward
- Based on what you just learned about ionization energies, explain why valence electrons are more important than core electrons in determining the reactivity and bonding in atoms.arrow_forwardDefine the terms nucleus and electron shell/orbital. Which subatomic particles are important for chemical bonds to occur?arrow_forwarduse the periodic table to predict the charge associated with ions of main group elements.arrow_forward
- What is electrostatic force? Use your understanding of electrostatic force and how the number of protons and electrons differ in atoms to explain the observed change in atomic size.arrow_forwardExplain how to find the number of valence electrons of an atom just by looking at the periodic table. Give an example.arrow_forwardFluorine (F) has atomic #9. Neon (Ne) has atomic #10. Which statement accurately compares the reactivity of these two atoms? * A:Neon is more reactive than Fluorine because it has more protons B:Fluorine is more reactive than Neon because its outer energy level is not full. C:Neon is more reactive than Fluorine because its outer energy level is not full. D:Fluorine is more reactive than Neon because it has more electronsarrow_forward
