what does the group number tell you about an element? how heavy it is how many neutrons it has how many total electrons it has how many valence electrons it has question 10 (1 point) which type of element is shiny and a good conductor? nonmetal metalloid metal gas

Answer

Brief Explanations:

  1. In the periodic table, the group number of a main - group element indicates the number of valence electrons. For example, elements in group 1 have 1 valence electron, and elements in group 17 have 7 valence electrons.
  2. Metals are known for their shiny appearance (luster) and are good conductors of heat and electricity due to the presence of free - moving electrons in their structure.

Answer:

  1. How many valence electrons it has
  2. Metal
