Proton

anything that has mass and can occupy space is called matter. Atoms are the main components that make up matters. Name the particles that are in different form in an atom; answer to this question is electrons, protons and neutrons. Where protons and neutrons are found in an atom? Answer: proton can be find in the nucleus, and electrons are located in the shells outside of the nucleus. Can someone in the class defines a molecule? Answer: A molecule is defined as the smallest part of a substance…

lightest of the alkali metals. The two main parts of every atom are neutrons and protons. The three main subatomic particles that form an atom are protons, neutrons, and electrons. Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center of the atom. Protons has mass (g) of1.673 x 10-24, Mass (amu) is 1 and location is…

The Atomic Theory states that all matter is composed of discrete units called atoms. The Atomic Theory started in about 400 BCE with a scientist by the name of Democritus. Democritus proposed the idea of the existence of an ultimate particle. He called this particle atomos when he was describing it, because the particle was too small to cut. Next, we get to Leucippus. Leucippus was the man who founded atomism, which is a theoretical approach that states nature consists of two principles, which…

Compacted in that small space are neutrons and protons that constantly jiggle. Neutrons are uncharged particles that add mass to the nucleus without adding a charge. The protons are positively charged particles that are also located in the nucleus and symbolized as p+. The second part of an atom is the electron cloud. The electron cloud is a cloud of electron which surrounds the nucleus. The electrons are the third type of subatomic particle- along with protons and neutrons. Located…

include gravitational, electromagnetic, strong, and weak. The electromagnetic force is the reason why the electrons are repelled from the nucleus and the protons. The strong force is why the protons stay together in the middle. These both keep the atom from falling apart. Weak forces keep radioactive decay from transforming the nucleus into a proton or an electron. Most commonly know is gravity. Gravity impacts the less on the atom compared to the rest of the forces. Gravity affects the tiny…

The diagram of the atom Carbon-12 represents an ion and an isotope. Carbon-12 has six protons and six neutrons in its nucleus, as shown on the diagram. Outside of the nucleus, this atom has five electrons. The protons are shown in the color orange, neutrons are in the color blue, and electrons in the color teal. The scientific principle subatomic particles says they are smaller than the atom itself, meaning protons with a positive charge, neutrons with a neutral charge, and electrons with a…

atoms, which are composed of small particles called protons, neutrons, and electrons. The nucleus of an atom is made of a tightly packed collection of protons and neutrons. You would think that with positively charged protons being packed so closely together the nucleus would fall apart, however this is not the case. There is an attractive force called the “nuclear force” which is able to overcome the repulsive force of the adjacent protons and holds the nucleus together. When the nuclear…

Alchemists used to obsess over chrysopoeia, the transmutation of regular metals, such as copper, into gold. However, they were not aware at the time that copper and gold were two different atomic elements and instead believed them to be compounds. Thinking these metals could be changed chemically or physically in labs, alchemists pursued this dream to no advantage. Although it is not possible to change ordinary metals to gold through chemical reactions, physical reactions, radioactive decay, or…

Atoms, ions, and isotopes are everything you eat, breathe and see. They are everywhere and everything is made up of them. The first person that aided in the discovery of the atom was Democritus in 400 BC. He is the one that named the atom. The word atom comes from the Greek word atomos which means indivisible. Aristotle which was another flossier in at that same time disagreed with him. He believed that matter could be divide infinitely without changing its properties. At that time more people…

The atomic theory has revolutionized the field of science. The ideas behind it began in the times of Ancient Greece. From there the ideas were put under trial, proven, disproven, and formed into what we now recognize as the atomic theory. Since the beginning of time, people believed that matter was made from a few fundamental building blocks. In ancient times, these fundamental elements were thought of as water, fire, earth, and air. Around 400 BCE, Democritus and Leucippus developed a…
