when particles of unreactive .... collide, they bounce off each other at high speed without any loss of energy. What word is supposed to be filled in on the dots?
Answer:
Groups
Explanation:
The groups determine if the atom is reactive or not, take the Noble Gases for example, they are very very very unreactive.
A substance that flows is called a

9. Imagine that one of your kitchen workers tells you that he believes your kitchen has a pest problem and
might be facing an infestation. While you trust this employee, you want to see for yourself. What would you
look for in trying to determine if you have a pest problem or not? Describe the key signs that you would look
for and what you would do if you determined that you were suffering from a pest problem.
Answer:
well there are many ways to prevent a pest infestation ..... as we all know ... insects such as ants love leftovers, so store food in airtight containers like Tupperware or jars with rubber seals on the lids.
Keep a tight lid on your trash can at all times and move the trash to an outside dumpster as soon as possible.
Clean your counter tops, tables, and floors on a regular basis to prevent crumbs or food buildup

Which statement best explains why mass is not conserved in a nuclear change?
Some of the products have less mass than the reactants.
Some of the reactants are not used.
Some of the atoms are lost in the reaction.
Some of the matter is converted to energy.
The statement that best explains why mass is not conserved in a nuclear change is that; "some of the matter is converted to energy".
In a nuclear reaction, mass is converted to energy. This is the energy that is given out when a new nuclide is formed during a nuclear reaction.
Generally, the scheme of a nuclear reaction is; Parent nucleus + Bombarding particle -------> Daughter nuclei + product particles + energy. This energy is obtained when mass is lost from left toi right in the reaction.
Hence, the correct answer is; some of the matter is converted to energy".

Is each ion stable? Explain.
Answer:
By satisfying the duet rule or the octet rule, ions are more stable.
Explanation:
Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable.
The octet rule states that an atom is most stable when there are eight electrons in its valence shell. Atoms with less than eight electrons tend to satisfy the duet rule, having two electrons in their valence shell. By satisfying the duet rule or the octet rule, ions are more stable.

What particles would you find in a nucleus of an atom
Answer:
The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.
