Matter and substance are definitely related. All substances
are matter but all matters are not substance. A matter can consist of numerous
substances. Matter is generally a loose term used in respect to a substance.
Any physical object can be casually called a matter. Matter and substance are
sometimes used for the same context, but it is completely wrong. Numerous
examples have already proved that a matter may or may not be a substance
depending on its physical nature, but a substance is always a matter.
Answer:
Explanation:
Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
Answer:
fluorine (F), and chlorine (Cl) because they are both halogens and belong to the same group in the periodic table
Explanation:
The pair of non - metals in the elements given that will have similar properties are chlorine and Fluorine.
This is because they both are elements commonly known by the group name Halogens which belong to group 7A.
Properties of halogens include;
- They are very reactive, have single covalent bonds and readily form other compounds.
- In the gaseous state, they will form diatomic covalent molecules.
Whereas, helium is a group 8 element, oxygen is a group 6 element while carbon is a group 4 element.
Answer: A
because electron mass is so small that they aren't accounted for the overall mass of an atom. Electrons are smaller than protons and neutrons.
