Electrons are in constant motion outside of an atom’s nucleus. The electron shell is the region that the electrons travel in (see Fig
Each shell holds an increasing number of electrons, beginning with electron shell 1, which holds a maximum of two electrons (see Table 2.6).. Maximum number of electrons in each shell, up to shell 7
When one shell fills to its limit, electrons are added to the next shell. In a neutral atom, the number of negatively charged electrons is equal to the number of positively charged protons.
Chemistry for Majors [6]
– State the periodic law and explain the organization of elements in the periodic table. – Predict the general properties of elements based on their location within the periodic table
As early chemists worked to purify ores and discovered more elements, they realized that various elements could be grouped together by their similar chemical behaviors. One such grouping includes lithium (Li), sodium (Na), and potassium (K): These elements all are shiny, conduct heat and electricity well, and have similar chemical properties
However, the specific properties of these two groupings are notably different from each other. For example: Li, Na, and K are much more reactive than are Ca, Sr, and Ba; Li, Na, and K form compounds with oxygen in a ratio of two of their atoms to one oxygen atom, whereas Ca, Sr, and Ba form compounds with one of their atoms to one oxygen atom

Halogens, transition metals, groups/meta • Assignments [9]
· Describe physical and chemical properties of halogens.. You’ve probably seen halogen lights like the ones pictured here
A halogen light differs from a regular incandescent light bulb in having a small amount of halogen gas inside the bulb. The gas combines chemically with the metal in the filament, and this extends the life of the filament
What is halogen gas, and which elements are halogens? In this article, you’ll find out.. Halogens are highly reactive nonmetallic elements in group 17 of the periodic table
Trends in Group 17 Elements Chemistry Tutorial [10]
Trends in the Physical Properties of Group 17 Elements. Consider the melting points and boiling points of the Group 17 elements as shown in the table below:
We can use the melting point and boiling point to determine the state of each element at standard temperature and pressure (25°C, 100 kPa).. So let’s take another look at the melting points (M.P.) and boiling points (B.P.) of the group 17 elements and decide which are gases, liquids and solids:
The melting point of a substance reflects the amount of energy required to weaken the forces of attraction between molecules (intermolecular forces), the higher the melting point the stronger the forces of attraction between the molecules.. We can infer that there is a gradation in the intermolecular forces acting between the molecules such that the strongest forces of attraction act between iodine molecules and the weakest forces of attraction act between fluorine molecules.
Naming Covalent Compounds [11]
As with ionic compounds, the system that chemists have devised for naming covalent compounds enables us to write the molecular formula from the name and vice versa. In this and the following section, we describe the rules for naming simple covalent compounds
Binary covalent compounds—that is, covalent compounds that contain only two elements—are named using a procedure similar to that used to name simple ionic compounds, but prefixes are added as needed to indicate the number of atoms of each kind. The procedure, diagrammed in Figure 2.13 “Naming a Covalent Inorganic Compound”, uses the following steps:
The prefix mono- (“one”) is used only when absolutely necessary to avoid confusion, just as we omit the subscript 1 when writing molecular formulas.. To demonstrate steps 1 and 2a, we name HCl as hydrogen chloride (because hydrogen is to the left of chlorine in the periodic table) and PCl5 as phosphorus pentachloride
Definition, Physical & Chemical Properties, Uses, Examples [12]
Non-metals are the elements which form negative ions by accepting or gaining electrons. Non-metals usually have 4, 5, 6 or 7 electrons in their outermost shell.
Some of then are even solid at room temperature like Carbon, sulphur and phosphorus.. Characteristic properties of non-metals are high ionization energies and high electronegativity
The following are the general properties of non-metals.. – The atoms of non-metals tend to be smaller than those of metals
Electron Configurations & The Periodic Table [13]
Four elements, hydrogen, carbon, oxygen and nitrogen, are the major components of most organic compounds. Consequently, our understanding of organic chemistry must have, as a foundation, an appreciation of the electronic structure and properties of these elements
According to the Aufbau principle, the electrons of an atom occupy quantum levels or orbitals starting from the lowest energy level, and proceeding to the highest, with each orbital holding a maximum of two paired electrons (opposite spins).. Electron shell #1 has the lowest energy and its s-orbital is the first to be filled
As we progress from lithium (atomic number=3) to neon (atomic number=10) across the second row or period of the table, all these atoms start with a filled 1s-orbital, and the 2s-orbital is occupied with an electron pair before the 2p-orbitals are filled. In the third period of the table, the atoms all have a neon-like core of 10 electrons, and shell #3 is occupied progressively with eight electrons, starting with the 3s-orbital
