Can you predict the properties of a compound?
Can you predict the properties of a compound by knowing the properties of the elements that make up the compound? No, the properties of a compound are usually different from the properties of the elements that make up the compound.
How does a compound behave?
Chemical compounds are formed when elements are joined by chemical bonds. These bonds are so strong that the compound behaves like a single substance. Compounds have their own properties that are unique from the elements they are made of. A compound is a type of molecule with more than one element.
How do you know if its a compound or an element?
Explanation: An element is a pure substance and is found on the periodic table. If you have more than one element chemically bonded, it is a compound.
What makes a compound possible?
A compound is a unique substance that forms when two or more elements combine chemically. A compound always consists of the same elements in the same ratio. If the same elements combine in different ratios, they form different compounds. Types of compounds include covalent and ionic compounds.
In what ways can you predict the behavior properties of an element?
The Periodic Table can predict the properties of new elements, because it organizes the elements according to their atomic numbers. Creating new elements is not a simple process. Scientists use a particle accelerator to smash light atoms into a thin metallic foil that contains heavier atoms.
How can you predict the chemical properties of an element?
Determining Chemical Properties using the Periodic Table. Chemical properties of each element are determined by the element’s electronic configuration, and particularly by its outermost valence electrons.
Can a mixture be made only of elements?
Note that a mixture: consists of two or more different elements and/or compounds physically intermingled, can be separated into its components by physical means, and. often retains many of the properties of its components.
Why do elements react to form compounds?
When elements react, their atoms join with other atoms to form compounds. Chemical bonds form when this happens, which involves atoms transferring or sharing electrons. New substances are formed by chemical reactions. When elements react together to form compounds their atoms join to other atoms using chemical bonds.
What are the characteristics of elements and compound?
Question 8
| Elements | Compounds |
|---|---|
| They have properties different from compounds they make. Example – Hydrogen & oxygen are combustible, but water is not. | They have properties different from elements that they are made of. Example – Hydrogen and Oxygen are gases, but they make up water which is liquid. |
How are elements combined to form a compound?
When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl).
What can be predicted about an element by knowing its group number?
They are arranged according to their atomic number, the number of protons (which in the case of atoms is also the number of electrons) of each atom. This being said, elements belonging to the same group have the same number of valence electrons, the outermost electrons involved in chemical reactions.
How do you predict the molecular formulas of ionic compounds?
This problem demonstrates how to predict the molecular formulas of ionic compounds . Predict the formulas of the ionic compounds formed by the following elements: First, look at the locations of the elements on the periodic table.
Is it possible to predict the products of a chemical reaction?
The short answer is NO. There is no single complete theory that is able to predict what products will result from combining a number of reactants. Note that the products of a chemical reaction are not only a function of the reactants, but also of temperature, pressure, catalyst present and several other factors.
How do you determine the charges of ionic compounds formed by elements?
To determine common ionic compounds formed by elements, keep the following in mind: Group I ions (alkali metals) have +1 charges. Group 2 ions (alkaline earth metals) have +2 charges. Group 6 ions (nonmetals) have -2 charges. Group 7 ions (halides) have -1 charges. There is no simple way to predict the charges of the transition metals.
How do you predict the charges of transition metals?
There is no simple way to predict the charges of the transition metals. Look at a table listing charges (valences) for possible values. For introductory and general chemistry courses, the +1, +2, and +3 charges are most often used.
