Atom history essay an atom is a basic unit of matter that consists of a dense, central nucleus surrounded by a cloud of negatively charged electrons the atom was theorized by a man named democritus of abdera, thrace in between ca 460 bc - ca 370 bc atom is derived from the greek word “atomos” , which means to be uncuttable. Prelab instructions: beginning questions: what are my questions about this experiment after reading the lab handout, write questions that can be answered by doing the lab. Compare properties of molecules formed from atoms in similar families for example, h2s versus h2o explain what is meant by the electronic structure of atoms how does knowing the electronic structure of atoms aid chemists in predicting chemical reactions format your paper consistent with apa guidelines.
- the electron configuration of element m is 281 (b) i - both atoms have the same number of proton of 6 6 - atom x has 6 neutron while atom y has 8 neutrons - both atoms are of the same element because the number of proton of both atom is the same. Electronic structure of atoms • to understand the electronic structure of atoms, one must understand the nature of electromagnetic radiation • the distance between corresponding points on adjacent waves is the wavelength (λ. Atomic structure essays the nucleus has more than 100 protons and more than 150 neutons, the nucleus is a very small part of an atom both the atom and the necleus can be thought of as spheres then both volumes of the atom can be compared with the volume of the nucleus alone, because the volume of.
Atomic structure: - the nucleus of an atom contains protons and neutrons around the nucleus are electrons arranged in shells all atoms of the same element have the same number of protons and neutrons an atom has no overall electrical charge the masses of protons and neutrons and electrons are incredibly small. The atoms of each element are all the same as each other the atoms of one element are different to the atoms of another element this is because they have different numbers of protons, electrons and neutrons how are the atoms of different elements different the atoms of each element have a certain number of protons, electrons and neutrons. Atoms, molecules, & elements essay 732 words | 3 pages atoms are the smallest entities which resemble the properties of an element and cannot be broken down into smaller parts molecules are formed when two or more atoms are combined this formation can happen in a variety of ways.
Atoms act the way they do because of their structure we already know that atoms are composed of protons, neutrons, and electrons protons and neutrons are located in the nucleus, and electrons orbit around the nucleus but we need to know the structural details to understand why atoms react the way they do.
Chapter 7: electronic structure of atoms exercises: sections 74, 75 : ionization energy and electron affinities 1 - electronic structure of atoms introduction.
