Answer:

A type of an atom which has a different number of neutrons but the same atomic number, therefore making it the same element. This atom would still have the same properties as well. (Ex: Vanadium-51 is an isotope of Vanadium that has 51 neutrons but still has 23 protons, as its atomic number is 23.)

Anton [14]
“If a certain metal is cooked, it will conduct electricity better”

- this is a hypothesis, since the statement is kind of vague...”certain metal”...and is written in an “if-then” format.

The amount of electric current that passes through a conductor is directly proportional to the voltage and is described as V = IR

- laws are usually scientific understanding that we’ve tested so much that we’ve come to a conclusion that can often be written out as a mathematical relationship. Hence, the “V = IR”

Electricity is the flow of electric charge in the form of electrons moving through a circuit

- this is a theory. I would give an explanation but I’m out of time.

Hope this helps

Explain why the grams of the nutrient molecules in a food do not add up to the total gram weight of the food.
leva [86]

When we talk about the gram weight of any food item, it may or may not include the gram weight of its different nutrient molecules. It may have different reasons to it. One of the reasons can be because the nutrient molecule might contain a large percentage or proportion of water. Also, the nutrient molecules might be insoluble or indigestible fiber so it does not add up to the total gram weight of food.

If an element is lustrous, brittle, and a semi-conductor, how would you classify it?
just olya [345]

Metalloid

Explanation:

If an element is lustrous, brittle and a semi-conductor, it is best classified as a metalloid.

Metalloids shares attributes of metals and non-metals.

  • They are often described as semi-metals as they do not share the full properties that makes a metal a metal.
  • Metalloids are lustrous but not malleable like metals.
  • They do not conduct electricity but they do so on certain conditions.
  • Examples are silicon, germanium, boron, arsenic e.t.c
  • They are usually found in the middle of the periodic table.
  • They are not readily alloyed with metals.
