You can classify a metal: when a subject can surely conduct electricity.
examples: if a problem says the unknown object is malleable, or says "on the left side of the periodic table", is a conductor, is shiny, etc.
Metalloids: when a subject is alongside the staircase, uses word "semi-conductor", it depends on if it's malleable or ductile, and depends on whether it's shiny or not, etc.
Nonmetal: is located on the right side of the periodic table, can ONLY be an insulator, is not malleable, is not shiny, etc.
To find the atomic mass of an isotope, simply multiply the fraction by the mass<span> number for each </span>isotope<span>, then just add them together.</span>
Answer:
D.
Volcanic eruptions act as constructive forces when lava builds up to form volcanoes and plateaus.
Explanation:
Volcanic eruptions brings lava to the surface. They are powerful constructive forces that builds the earth and adds new materials to the surface.
- Molten rocks from within the earth reaches the surface.
- They then build up and accumulate to form very interesting land masses.
- A constructive force adds new materials to the earth.
- Weathering is a destructive force.
- One notable constructive force usually occurs along divergent margins.
- The mid-oceanic ridge is a very fascinating example
I am not going to do your work for you. However, just a reminder that a science experiment must be able to yield the same results if done in the same conditions by another scientist.
Pros:
- It's green energy
- There is no CO2 released, so this doesn't add to the global warming crisis
- The only byproduct is steam, which is released back into the atmosphere
Cons:
- It uses uranium and that is carcinogenic to humans
- The uranium takes millions of years to become non-toxic
- Radioactive waste can leak and contaminate drinking water
