What does the atomic number of the atom tell us?

Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.

Most common atom in the world?

"The world" could be taken to mean the universe as a whole or Earth specifically.

The most common atom in the universe is hydrogen.

The most common atom in Earth's crust is oxygen.

Slightly more of the Earth's total mass comes from iron (about 32% iron, 30% oxygen), but since an iron atom is a bit over three times the mass of an oxygen atom, there are still more oxygen atoms than iron atoms in Earth as a whole.

How many atoms are there in 4H2SO4?

4H2SO4 = 4*(2(H)+1(S)+4(O)) = 4*(2+1+4) = 4*7 = 28 There are 28 atoms in 4 moles of H2SO4.

What does the atomic number of and atom give?

The atomic number of an atom indicates the number of protons that the atom has.

All atoms contain protons, neutrons and electrons. (The exception is hydrogen which has only one proton and one electron). It is the number of protons that defines the element. So, helium with an atomic number of 2 will always have 2 protons.

Normally, the atom will have the same number of electrons as protons but there are many instances where this is not the case.

The number of neutrons can vary in some atoms. Let us take carbon as an example: It has an atomic number of 6 so it has 6 protons and 6 electrons. Most carbon atoms have 6 neutrons but a very small number have 8 neutrons. Although they are the same element, they are two different isotopes known as carbon 12 and carbon 14.

The atomic mass of an element is approximately the mass of each proton, neutron and electron added together.

What was vulcanized rubber used for?

Things that use rubber (and also synthetic rubber) include:

tires, erasers, rubber bands, seals, gaskets, rollers, machine belts, cushioning pads, electrical insulation, bouncing balls, sports balls, and tool grips.

An explosion is a very fast kind of what?

Combustion reaction, or decomposition reaction.

Gunpowder explodes because the carbon and sulfur are burned rapidly making lots of expanding gases.

Nitroglycerine explodes because the molecules are unstable and decompose into more stable molecules, which are gases and must expand rapidly because any gas occipies more than 1000 times the volume of the liquid it comes from.

Atomic bombs are neither ... they release so much energy that they heat the air to nearly 1 million degrees and this causes the rapid expansion known as an explosion.

So maybe what you are looking for isn't a chemical answer, but just a very radip expansion of gases.

Is it safe to solder inside?

It is generally safe to solder inside as long as you work in a well-ventilated area to prevent inhaling fumes. It's important to wear safety gear such as gloves and eye protection to protect yourself while soldering. Additionally, be cautious of flammable materials nearby and use a heat-resistant surface to work on.

Where is aneutron found in a atom?

The neutrons make up the nucleus along with the protons. The electrons orbit around the nucleus in their energy levels. The neutrons has no charge or a neutral charge.

When did America officialy enter world war 2?

The United States declared war on Japan on 8th December 1941, the day after the Japanese attack on Pearl Harbour.

Why does a bomber not drop its bomb vertically above the target?

Dropping the bomb at an angle allows the aircraft to safely release the bomb from a distance, reducing the risk of being hit by enemy defenses. Additionally, releasing the bomb at an angle helps to achieve better accuracy by taking into account factors like wind speed and trajectory.

What is Meaning of explosively unstable?

It means something is highly volatile and likely to explode or change very quickly and uncontrollably.

Atomic number of fluortine?

Fluorine is a non meta element. Atomic number of it is 9.

Atoms come together to form?

Elements form together to create compounds such as H2O-water it is just two hydrogen and one oxygen. This is also known as dihydrogenmonoxide (said- di...hydrogen...mon..oxide), without this coumpound there would be no living oranisms

When was the first atomic explosion?

There has never been an atomic detonation to date in mexican territory. Since the country sponsored and signed the Treaty of Tlatelolco wich objective is to ban any nuclear based weapon in Latin America, it is still unlikely that Mexico would develop or test nuclear weapons.

What was the Army equivalent of the Navy's Sonarman Third Class SO3?

Navy Sonarman 3rd Class is an Petty Officer of the E4 pay grade equal to the Army Corporal E4. or E4 specialist

3 parts of the atom?

The electron (negative charge), the neutron (neutral charge), and the proton (positive charge). The neutrons and protons are both found in the nucleus of the atom, while the electrons are on the outside circling the atom.

Effects of man made disasters?

the meltdown of the chrenobyle(i know that isn't spelled right) nuclear power plant. the area is still uninhabitable and highly radioactive

This answer is just silly:

1) Genocide in China (1948-1976)

2) Genocide in the Soviet Union

3) Genocide in Cambodia

4) Holocaust

Just these four make Chernobyl look like a sunny day in the park.

How many uses are there for the atom?

Countless billions and maybe even infinity. Everything that you can see touch or smell all the matter in the world is made up of atoms. Even you are. Atoms are the building blocks of the world. Every star, being and thing is made of atoms.

What are the differences between the two bombs dubbed Fat Man and Little Boy?

In the Manhattan Project they worked on two different designs for nuclear weapons. The idea is to make a critical mass which causes a chain reaction. You do this by compressing the material violently with conventional explosives. The Little Boy used an internal cannon to shoot a projectile into a mass of uranium to compress it. The Fat Man used a sphere of plutonium surrounded by a 'shape charge' that would explode and compress it.

Why were people made?

In our Religion (Islam), People were made because God wanted friends. So he/she made people. But in our religion we have rules which are useful for life. Only 95% of people in this world are following them. If you want to know the rules read our Holli book, the Quran.

What is metal craft?

Metal craft is the creation of various objects and art pieces using metals such as iron, brass, copper, and steel. Techniques used in metal craft include forging, welding, casting, and etching, among others. Metal craft can produce a wide range of items, from functional objects like tools and utensils to decorative pieces like sculptures and jewelry.
