The purpose of this lab was to determine the atomic structure of small molecules and ions which we did by drawing Lewis Dot Structures, drawing molecular geometries, and using the VSEPR model on a computer. The VSEPR Theory states that molecular geometries of molecules can be predicted through their number of electron pairs on the central atom because these electrons will repulse each other as much as they can while still being bound to the central atom. The Lewis Dot Structures and the molecular

mass. The number of protons in the nucleus of the atom is equal to the atomic number. The number of electrons in a neutral atom is equal to the number of protons. Electrons are the smallest of the three parts that make up atoms. Both protons and neutrons are found in the nucleus. Electrons are sometimes found in the orbitals or the shells. The atoms of elements have different numbers. Every element has its own unique atomic number. That number tells you the number of protons in every atom of the

John Dalton was born in 1766 in England. At the age of 14 years old, Dalton became a teacher and taught at a Quaker school in his village, where he attended until eleven years old. “Dalton continued teaching himself science, mathematics, Latin, Greek and French.” At the age of 26, he taught mathematics and natural philosophy at Manchester’s New College. In 1794, he wrote his first scientific paper about color blindness. Although it was later proven wrong, he was the first to research about it. He

element. It is in the first period, in group 8 in the periodic table of elements. Helium is also a nonmetal. Its element symbol is He, and it has an atomic number of 2, and an atomic mass or molar mass of 4.003 amu. This means that helium contains 2 protons, 2 electrons, and 2 neutrons. Helium is the second most common element on the universe. Helium is a noble gas, a noble gas is a substance that does not have color, taste or odor, and they are not flammable. Noble gases were originally labeled as

The differences between "Energy Story, Conducting Solutions, and Hands-On Science with squishy circuits" are those two are articles and the other one is a video. Also The Energy Story talks about what is inside of an atom which are neutrons protons and electrons. When Conducting Solutions talk about ions. Like what they are what’s inside it and other questions. The video talks about how play dough

are made up of three microscopic components; a positively charged proton, a neutral neutron, and a negatively charged electron. The proton and neutron make up the nucleus (the center) which makes up the entire mass of the atom. The number of protons determines the atomic properties and the atomic number of the element. Protons also determine electron affinity; the atoms size depends on how attracted the electrons are to the protons. The electron(s) orbit around the nucleus; they orbit so fast that

atoms. Atoms are composed of protons which is the positive charged particles, neutrons is the neutral particles and electrons which it is the negatively charged particles. Protons and neutrons are located in the nucleus. Electrons are found in orbitals surrounding the nucleus. Negatively charged electrons circle the nucleus of the atom, while the nucleus is composed of positively charged protons and neutral neutrons. An atom's atomic number refers to its number of protons, while its atomic mass refers

are made up of electrons, protons and neutrons. Protons have positive charge; electrons have negative charge and neutrons are neutral. The magnitude of charges of protons and neutrons is the same. Protons and neutrons are found in the nucleus, while the electrons moves around it. Mass number is addition of the protons and neutrons. Atomic number is the number of protons. [1] The mass of an atom is less than the number we obtain by adding up the masses of all the protons and neutrons. This is the

soda. This gave him the new element that he named sodium after the word soda which is the collective name for several forms of sodium carbonate. The word “soda” likely came from the Arabic word “suda” which means headache. This element has eleven protons, eleven neutrons, and no electrons. This gives it an atomic number of eleven and an atomic mass of 22.989768. Sodium is a metal which means that it is an effective conductor of electricity as well as heat. Compounds of sodium had been known off

All magnets produce their own invisible magnetic field that’s unable to be seen with the naked eye, and each magnetic field interacts with other magnetic fields. Magnets are made of metals like iron ore, iron, or alloys, which is a mixture of metals, or of a metal and a nonmetal. Magnets only react with certain metals such as iron, steel, nickel, or cobalt. They have two poles, one of them is north pole, while the other is called the south pole. The opposite poles attract, while the same ones repel
