See more Calcium products. Calcium atomic symbol: Ca, atomic number: 20 is a Block S, Group 2, Period 4 element with an atomic weight of The number of electrons in each of Calcium's shells is [2, 8, 8, 2] and its electron configuration is [Ar]4s 2.
The calcium atom has a radius of pm and a Van der Waals radius of pm. How is it written? Give an example. What ions form when calcium reacts with bromine? What is the name of the ionic compound that results? What is the formula for this compound? Which classes of elements make up ionic compounds?
How are ionic compounds named? Describe properties of ionic compounds. The ionic compound sodium fluoride is added to toothpaste to prevent tooth decay. Describe the composition and structure of this compound. The burner on a gas stove burns with a pretty blue flame like the one pictured in the opening image.
The fuel burned by most gas stoves is natural gas, which consists mainly of methane. Methane is a compound that contains only carbon and hydrogen. Like many other compounds that consist of just these two elements , methane is used for fuel because it burns very easily. Methane is an example of a covalent compound.
Compounds that form from two or more nonmetallic elements , such as carbon and hydrogen, are called covalent compounds. In a covalent compound, atoms of the different elements are held together in molecules by covalent bonds. These are chemical bonds in which atoms share valence electrons. The force of attraction between the shared electrons and the positive nuclei of both atoms holds the atoms together in the molecule. A molecule is the smallest particle of a covalent compound that still has the properties of the compound.
The largest, most complex covalent molecules have thousands of atoms. Examples include proteins and carbohydrates , which are compounds in living things. The smallest, simplest covalent compounds have molecules with just two atoms. An example is hydrogen chloride HCl. It consists of one hydrogen atom and one chlorine atom, as you can see in the Figure below. You can watch an animation of hydrogen chloride forming at the following URL.
Give this second name the suffix —ide. The most commonly used prefixes are shown in the Table below. Q: What is the name of the compound that contains three oxygen atoms and two nitrogen atoms? A: The compound is named dinitrogen trioxide. Nitrogen is named first because it is farther to the left in the periodic table than oxygen.
Oxygen is given the -ide suffix because it is the second element named in the compound. The prefix di- is added to nitrogen to show that there are two atoms of nitrogen in each molecule of the compound. The prefix tri- is added to oxygen to show that there are three atoms of oxygen in each molecule. In the chemical formula for a covalent compound, the numbers of the different atoms in a molecule are represented by subscripts.
For example, the formula for the compound named carbon dioxide is CO 2. Q: What is the chemical formula for dinitrogen trioxide? A: The chemical formula is N 2 O 3. The covalent bonds of covalent compounds are responsible for many of the properties of the compounds. Because valence electrons are shared in covalent compounds, rather than transferred between atoms as they are in ionic compounds, covalent compounds have very different properties than ionic compounds.
In contrast, many ionic compounds do not burn. This explains why many of them are liquids or gases at room temperature. You can compare the boiling points of some covalent and ionic compounds in the Table below.
For a compound to be a liquid at room temperature, what does its boiling point have to be? Water is an example of a covalent compound that is a liquid at room temperature. Covalent compounds have relatively low boiling points, cannot conduct electricity, and may not dissolve in water.
