convergent boundaries: this is an area on earth where 2 or more lithospheric plates collide. they will slide under one another creating a subduction.

transform boundaries:  transform boundary is a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone.

lithosperic means the solid outer part of the earth.

What the answer for number 7
Alexus [3.1K]

Antimony Sb

Explanation:

The element that will have similar chemical properties with Arsenic As is element Antimony or Sb.

An element is a distinct substance that cannot be split-up  into simpler substances. They are made up of only one kind of atom.

  • The chemical properties of an element is determined mostly by the number of electrons in its outermost shell.
  • This is called the valency of an element.
  • Element having the same valency behaves the same way chemically.
  • They exchange the same number of electrons during chemical reaction.

Therefore, elements in the same group on the periodic table have the same chemical properties.

Elements in the same group have the same valency.

Anitmony and Arsenic belongs to group 5 on the periodic table. The elements in this group are Phosphorus, Arsenic, Antimony and Bismuth.
