Asap! 20 points brainliest if right elements in the same ? have the same number of valence electrons. elements in the same ? have the same number of electron shells. metallic elements become ? reactive as you move left to right in a period. metallic elements become ? reactive as you move top to bottom in a group.

Elements in the same Group have the same number of valence electrons.

Elements in the same Period  have the same number of electron shells.

Metallic elements become Less reactive as you move left to right in a period.

Metallic elements become More  reactive as you move top to bottom in a group.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
