The Basics of the Atom

Before we start on Niobium, we need to talk about the 

atom first. There are three particles in the atom: electrons, 

neutrons, and protons. Inside the Nucleus has the protons 

and neutrons outside the nucleus is the electrons inside the 

electron cloud.The electrons aren't always the same 

distance to the nucleus because there are different levels 

of the electron cloud. The particles that are mainly involved 

in chemical reactions are valence electrons. Nuclear 

reactions may release a large amount of energy. Not all 

atoms have the same amount of protons. In fact there is a 

table that separates the elements based on there amount 

of protons or the atomic number. This table is called the 

periodic table. The way you find the amount of protons, 

electrons and neutron is, to find the Protons and electrons 

look at the atomic number, the number is the same 

amount of protons and electrons. The neutrons is the 

atomic number- atomic mass.

This is a diagram of periodic table 

box each element has its own bow 

with its mass and name in it.

Niobium

Now that we know the basics of an Atom we get to 

learning about our element Niobium. So first off 

the Atomic number is 41, The Atomic mass is 93. 

Next the symbol is Nb. The person who discovered 

it was someone by the name of Charles Hatchet in 

1801. This element looks white and is a solid. 

Common uses for this element is in Alloy like for 

missiles and space equipment. Also it can be used 

for MRI magnets. Health effects can be, Inhaling 

the Niobium dust can cause poison. There aren't 

any environmental effects known.

Compounds of Niobium

One compound of Niobium is Niobium Oxide 

which has the formula of NB0 it is a super 

conductor. Another Compound of Niobium is 

Niobium Dioxide, NbO2 this is used for a 

powerful reducing agent. It changes carbon 

monoxide to just carbon. It changes Sulfur-

Dioxide to just Sulfur. Those are both 

compound of Niobium.

Glossary

Nucleus: /ˈn(y)o͞oklēəs/, The positively charged 

central core of an atom, containing most of its 

mass.

Protons:/ˈprōˌtän/,A stable subatomic particle 

occurring in all atomic nuclei, with a positive 

electric charge equal in magnitude to that of 

an electron.

Neutron: /ˈn(y)o͞oträn/, A subatomic particle of 

about the same mass as a proton but without 

an electric charge, present in all atomic nuclei 

except those of ordinary hydrogen.

Electrons: /iˈlekˌträn/   A subatomic particle with 

a charge of negative electricity, found in all 

atoms and acting as the primary carrier of 

electricity in solids.

Electron Cloud:The region of negative charge 

surrounding an atomic nucleus.

Valence Electrons: electrons of an atom that 

can participate in the formation of chemical 

bonds with other atoms.

Atom:a basic unit of matter.

Atomic Number: the number of protons found 

in the nucleus of an atom.

Atomic Mass: total mass of protons, neutrons 

and electrons in a single atom.

Symbol: The symbol that the element is 

referred to.
