Because their atoms have the same number of electrons in the highest occupied energy level
Ionization energy is the energy needed to remove one electron from an atom in the gaseous state.
Ionization energy (IE) is the force needed to ionize a neutral atom or cation when it is in its gaseous state. Ionization potential is another name for IE. Ionization energy is conceptually defined as an element's affinity for its outermost electron (an electron it already has in its valence shell).
The least amount of energy needed to ionize an atom is needed to remove an electron from its ground state. Across the periodic table, there is a regular increase in ionization energy from top to bottom and left to right.

Answer:
C. An atom consists of positively charged matter that contains negatively charged particles.
Explanation:
Answer:
Hydrothermal solutions
Explanation:
Vein deposits which cuts through rock layers are usually products of hydrothermal solutions.
Veins are rich ore deposits in which superheated water rich in dissolved minerals penetrated through a rock body and the minerals becomes precipitated and deposited in the process. Most veins have small width and a great length. Some occurs as veinlets depending on the nature of the weaknesses they trace out in a rock body.
Veins contains minerals such as gold, copper ore, rare earth metals. Most hydrothermal solutions contains minerals that are not compatible with the melt as rocks crystallize. They preferred to be carried with super heated water which deposits them seperately.
