1: An atom is nuclear energy that is extremely small. It is the smallest unit of matter that forms a chemical element. It is the building block for all matter in the universe. They are made up of even smaller particles. Particles that make up an atom are electrons, neutrons, and protons.
2. What’s different inside of an atom to make them into different elements is that the number of protons in an atom is the defining feature of an atom. This is what makes a element different from another.
Hope this helps!!
Answer:
The missing reagents are.
Potassium + Iodine =<u> Potassium iodide</u>
<u>Calcium</u> + oxygen = Calcium oxide
Beryllium +<u> Bromine</u> = Beryllium bromide
<u>Copper + Oxygen</u> = Copper oxide
Explanation:
The balanced equation can be written as:
1.Potassium + Iodine =<u> Potassium iodide</u>

Here K = potassium
I2 = Iodine
KI = potasssium iodide.
2.<u>Calcium</u> + oxygen = Calcium oxide

Ca = calcium
O2 = oxygen
CaO = Calcium Oxide
3.Beryllium +<u> Bromine</u> = Beryllium bromide

Here,
Be = beryllium
Br2 = bromine
BeBr2 = Beryllium Bromide
4. Copper + Oxygen = Copper oxide

Cu = Copper
O2 = oxygen
CuO = Copper Oxide
Answer:
E....H+
Explanation:
coz when hydrogen ions are formed they automatically join to form hydrogen
