Answer:
Electrons are negatively charged particles that orbits the nucleus
Explanation:
Chemical and physical properties of elements are usually determined by the number of electrons they posses. When atoms combine, they do so in order to attain stability.

Explanation:
-The molar mass of copper is 63.546 grams.
-We obtained the mass of 0.762 moles of copper:
![mass =moles\times molar\ mass\\\\\\=0.762\times 63.546\\\\=48.422\ g](https://tex.z-dn.net/?f=mass%20%3Dmoles%5Ctimes%20molar%5C%20mass%5C%5C%5C%5C%5C%5C%3D0.762%5Ctimes%2063.546%5C%5C%5C%5C%3D48.422%5C%20g)
-We apply the specific heat formula to calculate the amount of heat released:
![q=mC\bigtriangleup T\\\\\\=48.422\ g\times 0.385 \ J/g\textdegree C\times (81.6-52.2)\textdegree C\\\\\\=548.089 J](https://tex.z-dn.net/?f=q%3DmC%5Cbigtriangleup%20T%5C%5C%5C%5C%5C%5C%3D48.422%5C%20g%5Ctimes%200.385%20%5C%20J%2Fg%5Ctextdegree%20C%5Ctimes%20%2881.6-52.2%29%5Ctextdegree%20%20C%5C%5C%5C%5C%5C%5C%3D548.089%20%20J)
Hence, the amount of heat released is 548.089 J
Answer:
Silicon atoms have 14 protons.
Silicon atoms will react with other atoms in order to gain stability.
Silicon atoms have 14 electrons.
Explanation:
During a chemical change, a new kind of matter is formed. Examples are combustion, rusting of iron, precipitation and souring of milk.
Here are some of the properties of chemical change:
- They are not easily reversible
- It leads to the production of new kinds of matter.
- It involves change in mass.
- It requires a considerable amount of energy.
