How Does Atomic Radius Affect The Reactivity Of Elements
First of all reactivity is how fast electrons can be gotten rid of. Atomic radius is a major factor which illustrates reactivity based on the size of orbitals located in the atoms. Looking at the periodic table, I can tell that by going left and right and up and down, the atomic radius increases. Hence, calcium would have a higher atomic radius than magnesium which would also be higher than aluminum. Atomic radius affects the reactivity of elements because if an element has a small atomic radius, the electrons in the outermost orbital will be very close to the protons near the nucleus, making the protons have a tighter grip on the electrons ultimately making it both harder and slower to remove electrons. This is unlike a large atomic
Chemical Elements Lab Report
514 Words | 3 PagesThe chemical elements are divided into two broad groups, the metals and the non-metals. In this experiment, you will examine some members of the metal group and identify similarities and differences in their physical and chemical properties. Metals are the elements that are found in the left of the periodic table with high electrical and thermal conductivity. Metals lose electrons to create positive ion charges. Metals have a unique shine, are prone to forming, have a high tendency to form cations, and combine with oxygen to give mostly basic oxides.

The atomic radius does the opposite of electronegativity and ionization; it decreases as the elements go across the periods and increases when the elements go down the groups. The electronegativity increases as you go across the periods because the elements nucleus gains 1 more proton which means more protons more power to attract the electrons, the electronegativity decreases as you go down the groups because an extra shell is added every time this then causes an increase in nuclear charge due to more protons being added. This means that the nucleus is less able to attract electrons. Ionizing energy increases across a period because as the atoms radii is getting smaller the electrons get closer to the nucleus which creates a greater attraction for the electrons making it harder to remove them.

761 Words | 4 PagesA mixture of elements is what is known as compounds. Chemical reactions occur when particles react with each other and atoms in molecules get rearranged. Reactions happen either rapidly or slowly. The speed of a reaction is known as the rate of the reaction. This speed of chemical reaction depends on many factors such as temperature, particle size of reactants, and the intensity of reactants.

Geochemists afterwards operate a device called a handheld X-Ray Fluorescence (XRF), which works in a very similar manner to the commonly seen bright neon lights, to conclude the identity of minerals in the land. Atoms (microscopic building blocks of all matter) consist of electrons that move around it in orbits- similar to how planets orbit the Sun. These orbits increase in the total energy of electrons as they move farther from the ‘nucleus’, or the centre of the atoms. Light beams inside this device replace these orbits so that some unique frequencies of energy are released.
Libs 4960 Atomic Theory
526 Words | 3 PagesSomalie Prak LIBS 4960 Dr. Katie Olivant Chemistry Chemistry is a study of fundamentals of inorganic chemistry. This course is designed to provide you with basic understanding of chemistry and prepare you for more advanced chemistry courses. One concept that I learned in this course was the Atomic Theory. This theory suggests that all matter is made up of tiny indivisible particles that are called atoms. Atoms can be defined as the basic unit of a chemical element or the basic building blocks of matter that make up everyday objects such as a chair, or a table.
History Of Atom Dbq
375 Words | 2 PagesAtoms DBQ Atoms make up every object , substance, and material we know of(O.I). An atom is the smallest particle an element can be divided into. An atom has a complex structure, and the knowledge we have of it has changed many times throughout history. This tiny maze of parts has helped us learn important ideas about the structure and study of microscopic particles(O.I).

853 Words | 4 PagesSome factors that influence the speed of a chemical reaction are: (1) surface area of starting reactants; (2) concentration of reactants; (3) temperatures. The particle theory states that a solute dissolved takes place at the surface of the solvent and the larger the surface area of the particle the longer it will take to dissolve. The smaller the area the faster it will

1195 Words | 5 PagesAs the size of the radii atomic increased the further away the electron got from the nucleus. This also reduces the electrostatics attraction between the electron and the nucleus which means the electrons becomes more reactive. Therefore the reactions while going doing the list of group 1 elements increase.

Robert Oppenheimer On The Atomic Bomb
480 Words | 2 PagesMany of the scientist believe that the atomic bomb is not made very well and should not be dropped. During his speech , Robert Oppenheimer says, “Well, we know that atomic weapons are in principle possible, and it is not right that the threat of their unrealized possibility should hang over the world.” This quotation emphasizes the fact that knowing that an atomic bomb could be dropped at any second on your country is a very frightening situation. Certainly, a lot of people are scared from thoughts like war and death.

The atoms are currently being smashed at light speed and it is possible for a black hole to be produced. The European Organization for Nuclear Research believes that there is no threat of a black hole swallowing the earth. They know that it is a possibility that a black hole could be created but believe that it
Lead Is More Active Due To Most Active Out Of Three Metals
321 Words | 2 PagesReferencing our data, it can be determined that out of the three metals, Pb, Cu and Zn, it is shown that Lead (Pb) is more active than Copper (Cu) due to single-replacement reaction that took place. Lead had replaced Copper in the solution. Zinc (Zn), however, had replaced Lead thus leaving Copper to be the least active leaving Zinc to be the most active out of the three. In order of activity from least active, to most active, the metals would be lined up as following: Ag, Cu, Pb, Zn, Mg. From this lineup, it was be determined that hydrogen is more active than the elements silver and copper yet less active than zinc and magnesium.

Practically the materials in nanoscale have only few atoms or the clusters of atoms, and the properties of the materials have been found to be altered because of the quantum confinement effect. Nanomaterials have structural features in between to those of atoms and bulk materials. Nanomaterials exhibit a diversification of properties that are different and often significantly improved in comparison with those of
