Lab Activity: Periodic Trends – Atomic Radius. Some properties of elements show repeating patterns on the periodic table. This is called . periodicity. One of these properties is . atomic radius. Atomic radius is the distance from the nucleus of an atom to its outermost electron/orbital. Procedure:

In a similar fashion, evaluate the trends for the number of valence electrons of the main group elements, electronegativity, density (g/cm3), and melting point (°C) as a function of …

Explain how the names and symbols of elements are derived. Identify common metals, nonmetals, and metalloids, and noble gases. PROPERTIES OF ELEMENTS RELATE TO ATOMIC STRUCTURES . The periodic table shows all the elements. The periodic table is organized by properties. Group - a series of elements that form a column in the periodic table. Period

This approach proved incorrect, as it would have placed some elements in a family with dissimilar properties. Henry Mosley the table rearranged the table on the basis of the atomic numbers of the elements. I accordance with Mosley’s revision, the periodic law states: the properties of the elements are periodic functions of their atomic numbers.

Elements have distinct properties and atomic structure. All matter is comprised of one or more of over 100 elements: a. the structure of the atom and how it is composed of protons, neutrons and electrons. 9. Scientific progress is made by asking meaningful questions and conducting careful investigations.

Vertical columns of elements are called “groups” (18 total groups). All elements in a group have similar chemical and physical properties. Mendeleev published the first widely accepted periodic table in 1869. He arranged the elements in order of increasing atomic mass (different from how we do it today).
The Periodic Properties of the Elements
looks a lot like Mendeleev's, except it is arranged by atomic number (the number of protons) instead of atomic mass (the average mass of atoms of an element). Obj. 3.2 Predict similarities in properties of the elements by using the periodic table. Elements within a column (called a group or …

The purpose of this lab is to observe how certain properties of elements tend toward a periodic similarity when the elements are arranged in order of increasing atomic number; to note that elements (and ions of those elements) in the same vertical column (family) of the periodic table have similar properties; to note that elements (and ions of ...

This is why the atomic weight of carbon is 12.011 and not 12.00. (Most carbon is C12 , however about 1.1% of naturally occurring carbon is C13) amu – atomic mass unit approximately equal to the mass of a proton or a neutron. Strictly speaking, it is defined to be 1/12 of the atomic mass of C12 - the isotope of carbon with 6 protons and 6 ...
