Which pattern(s) may be observed from the arrangement of elements in the periodic table? Select all that apply.

A. increasing number of protons
B. similarity in the number of their valence electrons
C. similarity in their physical and chemical properties
D. increasing relative abundance on Earth's surface

Respuesta :

Answer:

A, B, C.

Explanation:

The periodic table exemplifies the number of protons for each element, the number of valence electrons for each element, and depending on the specifications and the complications of the periodic table (in other words the higher quality of a periodic table) will also commend upon you physical and chemical properties of each element and each group of which they belong to. Hopefully this helps.

The pattern(s) may be observed from the arrangement of elements in the periodic table -

  • A. increasing number of protons
  • B. similarity in the number of their valence electrons
  • C. similarity in their physical and chemical properties

The periodic table has various types of patterns in their arrangement of elements.

  • As you move to the right, the atomic number increases, meaning the number of protons increases.
  • The number of valence electrons decreases from left to right across each period.
  • The number of valence electrons increases from top to bottom within each group
  • Each element within a group has similar physical or chemical properties because of its atom's outermost electron shell

Thus, the correct choices are - A, B, and C.
