Chemical Reaction Essay

O and S belong to the same group. How many valence electrons does each have?

The three elements that I will be looking at are Krypton, Arsenic, and Potassium. These elements are all very different but share some similarities even with their separate placement on the periodic table. I chose these elements because they are the most different of the six elements that I chose to do this project on. Arsenic is the first element we will be looking at. Arsenic is a metalloid because it shares some characteristics with metals and some with nonmetals.

Purpose: The purpose of this experiment is to observe a variety of chemical reactions and to identify patterns in the conversion of reactants into products.

chemical element here on our own planet Earth. Though it is a rare, unreactive noble gas,

These different elements

Nonmetallic properties tend to predominate for elements at the far right portion of the table.

The fourth most abundant and by far one of the most interesting elements, Neon, is definitely unique. The tenth element on the periodic table is known as a noble gas, with the symbol ‘Ne’. This element has a density of 0.0008999 g/cubic meter, a boiling point of -246.08 degrees Celsius, three natural isotopes, an atomic mass of 20.179, and a melting point of -248.59 degrees Celsius. It’s atomic number is ten, and its atomic mass is 20.179.

the elements above and below in the periodic table, sulfur and tellurium” are saying that this

Noble gases are the most stable elements of the periodic table. They have many qualities that make them unique to other elemental groups. Noble Gases have many important differences that should be noted when studying the periodic table; such as the number of valence electrons and location, their state of matter, and their reactivity.

There have been many elements that have been discovered in this world. The two latest elements that have been discovered are ununquadium and ununhexium. Ununquadium is element number 114 on the periodic table. It was given the official name of flerovium by the IUPAC in 2012. Ununhexium is element 116 on the periodic table. It was given the official name of livermorium by the IUPAC in 2012. There are two other elements that have been discovered, but not yet confirmed. Those elements are ununtrium and ununpentium. Ununtrium is element 113 on the periodic table and it has no official name yet. Ununpentium is element 115 on the periodic table and also has no official name yet.

Group 1- hydrogen: lightest element on the periodic table. lithium: lithium never occurs freely in nature. sodium:Sodium is the sixth most abundant element in the Earth's crust,. potassium:Potassium ions are necessary for the function of all living cells. rubidium: Rubidium has also been reported to ignite spontaneously in air. caesium:the element is only mildly toxic, it is a hazardous material as a metal and its radioisotopes present a high health risk if released into the environment. francium:Francium is the most unstable of the naturally occurring elements

Elements exist all around us. There are actually one hundred and fifteen elements. Ninety of these one hundred and fifteen are naturally occurring. Metals make up ninety one of the one hundred fifteen elements. One element that fits all these characteristics; weighing in at thirty five point thirty nine grams, having an atomic number of thirty and grouped into group twelve on the periodic table, is none other than zinc.

The objective of this experiment is to experimentally investigate which elements show similar chemical properties.

The last thing is Nitrogen is the first element of Group V main group elements, a group that is called the nitrogen group. The nitrogen atom has five electrons in its outermost electron shell. Nitrogen is a colorless, odorless gas which is found as a two-atom molecule in nature. The two nitrogen atoms are joined by a triple bond. Each nitrogen atom has one unbounded electron pair. Nitrogen was recognized as one component of air in 1777 by C.W. Scheele. At the time, it was found not to be essential for either combustion processes or organism respiratory functions. It is almost completely insoluble in water. It does

This is a simple equation that doesn’t properly prove the reaction. It is very complex and starts with this:
