Solution Steps

Step 1: Analyze the options

The options provided are related to the properties of elements in the periodic table. They talk about metallic character, valence electrons, and electron configuration.

Step 2: Evaluate each option
  • They are all nonmetals: This statement is not universally true for all elements.
  • They have the same number of electrons: This is also not true. Elements are defined by their atomic number, which is the number of protons. Neutral atoms have the same number of electrons as protons, but ions have differing numbers of electrons.
  • They are all metals: Some elements are metals, some are nonmetals, and some are metalloids.
  • They all have 4 valence electrons: This would imply elements are in the same group (column) of the periodic table (specifically group 14).
  • They have identical electron configurations: This is incorrect. Each element has a unique electron configuration.
Step 3: Interpret the question

The question implies a common characteristic among a group of elements. While the image is blurry, the options seem to relate to concepts of periodicity.

Final Answer

\\(\boxed{\text{They all have 4 valence electrons}}\\)
