Answer:
alkaline earth metals
Group 2 metals, the alkaline earth metals, have 2 valence electrons, and thus form M2+ ions. The halogens, Group 17 , reach a full valence shell upon reduction, and thus form X− ions
Explanation:
<span>It takes only one atom to make hydrogen; however, hydrogen is commonly found as H2, meaning two atoms make up hydrogen. Because of this, hydrogen is known as a diatomic element
The answer is prob A.1 but you didnt' give me a formula.</span>
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
Answer:What is the first law of thermodynamics and how does it relate to energy use? The first law of thermodynamics states that energy is conserved in chemical processes. ... This amount of energy that must be lost to the surroundings for the process to occur is nature's heat tax, an unavoidable cut of every energy transaction.
Explanation:
Because of it's low resistivity, aluminum would be as safe as the copper.
<h3>What is the effect of conductivity on a material?</h3>
The conductivity of a material is the ability of a material to allow electric current to pass through it.
The conductivity of a material is inversely proportional to the resistivity of the material.
The higher the conductivity of material, the lesser the resistivity.
Aluminum has a lower resistivity than copper and therefore would be as safe as the copper.
In conclusion, the conductivity of a material is the inverse of it's resistivity.
