Answer:
cubic measurements
Explanation:
i.e. cubic meter or cubic centimeter
Answer:
6.022 X 10^23
Explanation:
avatars number states that for every mole of an element there are 6.p22 X 10^23 atoms of that element
Answer:
more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
Touch can sense the texture, and you can see what color it is, but if your talking about chemical properties, I'd say smell, color, and heat can identify some chemicals.
Answer:
B
Explanation:
We are talking about the periodic table in which elements where put under different rows and columns according to their atomic number (number of protons) in ascendant order.
In rows or periods we can find trends in some properties like atomic radius, electronegativity, etc...). So they are not similar in size. Option A is a false statement.
Also, they were organized in groups or columns according to their similar electronic configuration and chemical properties (like noble gases, halogens, etc...) This means option B is the correct statement.
