How may a chemical formula differ from an empirical formula?
CH2O = Empirical formula for carbohydrates. The ratios of the diggerent atoms are shown here and with a skeleton formula. C6H12O6 - Glucose, the actual carbohydrate with a full elemental complement.
What ion would the selenium atom shown below bond with to form a stable ionic compound?
The selenium atom shown below has 2 extra electrons, so it would likely bond with an atom that needs 2 electrons to fill its outer shell. For example, selenium could form a stable ionic compound by bonding with an atom like oxygen, which has a tendency to gain 2 electrons to achieve a full outer shell configuration.
What are two things that are shown by a chemical formula?
Scientist combine the symbols for different elements when they write chemical formulas.
What is the chemical formula of ethane?
C2H6 is the structure of ethane although the chemical formula can be shown in the displayed formula as well. This is shown by 6 C-H single bonds and 1 C-C single bond as carbon needs 4 bonds to other atoms.
Why does oxygen have a subscript of 3 in aluminum oxide?
Aluminum loses three electrons to have a full valence shell. Oxygen gains two electrons to have a full valence shell. Aluminum Oxide is shown as Al2O3 because there are three oxygen atoms with a total of 6 gained electrons. Two Aluminum atoms lose 6 electrons and three Oxygen atoms gain six. This is the balance between aluminum and oxygen.
What is shown by the structural formula of a polyatomic ion?
The structural formula of a polyatomic ion shows the arrangement of atoms within the ion, including their connections and bonds. It provides information on the overall charge of the ion and the distribution of electrons within the ion's structure.
What is a composition of a compound shown by?
The composition of a compound is shown by its chemical formula, which represents the types and number of atoms present in the compound. The chemical formula provides information about the elements present in the compound and their ratio, allowing for identification and understanding of the compound's structure and properties.
Which structural formula represents 4 electrons shared between two atoms?
A covalent bond that shares four electrons has a double bond between the atoms. A single bond is shown as a single dash, so a double bond is two dashes.
How is a structural formula shown for a triple bond?
A triple bond is typically represented in a structural formula by three parallel lines between the atoms involved. For example, in ethyne (acetylene), the structural formula showing a triple bond between two carbon atoms is HC≡CH.
The element that make up a compound and the exact number of atom of each element in a unit of the compound can be shown in a?
The exact number of atoms of each element in a unit of the compound can be shown in a chemical formula. Through the use of symbols, a chemical formula represents the proportions of atoms in a compound. For example, the chemical formula for water H2O indicates there are two hydrogen atoms and one oxygen atom.
How may a chemical formula differ from an empirical formula?
CH2O = Empirical formula for carbohydrates. The ratios of the diggerent atoms are shown here and with a skeleton formula. C6H12O6 - Glucose, the actual carbohydrate with a full elemental complement.
What is the difference between Lewis symbol and Lewis structure?
The difference between the Lewis dot structure and the structural formula is that the formula only shows the bonds that have formed whereas the dot structure shows all the valence electrons, including lone pairs, in that molecule.
What ion would the selenium atom shown below bond with to form a stable ionic compound?
The selenium atom shown below has 2 extra electrons, so it would likely bond with an atom that needs 2 electrons to fill its outer shell. For example, selenium could form a stable ionic compound by bonding with an atom like oxygen, which has a tendency to gain 2 electrons to achieve a full outer shell configuration.
How many atoms are shown in formula FeO of iron?
The formula FeO represents one iron (Fe) atom and one oxygen (O) atom, totaling two atoms in the compound.
What are two things that are shown by a chemical formula?
Scientist combine the symbols for different elements when they write chemical formulas.
The elements that make up a compound and the number of atoms of each element in a unit of the compound can be shown in a?
A molecular formula shows this information. In sulfuric acid, for example, the formula is H2SO4 as you'll learn to write it. There is hydrogen (H), sulfur (S) and oxygen (O) in it, and there are specifically 2 atoms of hydrogen, one atom of sulfur, and 4 atoms of oxygen. You already guessed (and correctly!) that those numbers, the numerical subscripts, tell an investigator how many of those particular atoms are in the molecule of sulfuric acid.
What is a semi condensed formula?
A semi-condensed formula is a shorthand way of representing a molecule's structure where covalent bonds are shown but not all atoms or bonds are explicitly drawn. It strikes a balance between a fully condensed formula (where only bonds between atoms are shown) and a structural formula (where all atoms and bonds are depicted).
