When a cation has more than one ionic charge what is used in the name?
When a cation has more than one possible ionic charge you use either just the number (i.e. 2+) if it is in ion form or a roman numeral (II) in a name.
The kind of eyes that insects have?
Insects can have a number of eyes and moreover, eyes of different types; single eyes and compound ones. In contrast with our eyes, insect eyes are immovable and unable to focus. Insects are short sighted. Butterflies are probably the most far sighted, they can see perhaps a few meters, while bumblebees only have a range of a half meter. But many insects are helped a lot by their sometimes unbelievable sensitivity for scents.
What is oligosaccharides?
Oligosaccharides are compound from sugar class which in their molecular structure entering a small amount of identical or different units of monosaccharides,which link together by glycosidic link.Oligo means a few or short . Sooligosaccharides means a few number of sugar inchain.
Is googleplex the largest number?
No. There is no such thing as a "largest number". Gogoolplex is a finite number. If you add one to a finite number, you get a larger number. In the case of an infinite number, if you raise 2 to the power of such a number, you get a larger number.
What is a multiplyer?
a multiplier is a number that you multiply by another number
Is NaCl an atom or molecule?
Neither. NaCl is an ionic compound and does not form molecules. It forms a crystal lattice in which every ion is surrounded by six ions of opposite charge. The formula NaCl is a formula unit which gives the simplest whole number ratio of ions in the compound.
What is coordination number of Na in Na2O?
Na + cation is surrounded by four oxide ion in Na2O and O 2- ion is surrounded be eight Na + ion.So co-ordination number of Na=4. DHK, Er.DHIRAJ KUMAR B.Tech IIT KANPUR
When is it appropriate to use parentheses in the naming of an ionic compound?
When the compound contains an ion with more than one atom in each ion, and the number of such units in a formula unit of the ionic compound is at least 2, parentheses are needed in the formula of the compound. In more conventional naming, parentheses containing a Roman number are often used after the name of a cation to denote its oxidation state, particular for atoms that form more than one stable cation.
Atomic no. of the cation?
The atomic number of the cation is the same as the atomic number of the neutral atom.
What is the coordination number of each type of ions in a rock salt type crystal structure?
Six. Explanation: Rock salt (NaCl) is ionic crystalline compound having Na+ and Cl- ions. Each Na+ is surrounded by 6 Cl- ions and vice versa. Coordination number for an ion is the number of oppositely charged ions around it. So it is 6.
Why do you never find an individual sodium chloride molecule by itself?
Sodium chloride is an ionic compound and does not form molecules. Sodium chloride forms a crystal lattice in which each ion is surrounded by six ions of the opposite charge. The chemical formula of sodium chloride, NaCl, represents a formula unit, which is the smallest whole number ratio of ions in the compound.
What is the oxidation number of each ion in MgBr2?
Magnesium is a divalent cation, with oxidation number +2, and bromide is a monovalent anion, with oxidation number -1 for each of the two ions. Thus the compound is electrically neutral.
Is copper 2 sulphate in ionic bound?
Copper (II) Sulfate, is an ionic compound. If that is what you are asking. Anytime you have a metal that has a number in parenthesis after it, you're going to be using ions. The number in paranthesis is what indicates the charge on the ion. For example, Copper (II) would have a charge of +2.
What do you know about a chemical compound by looking at its chemical compound?
the number and kinds of atoms in the compoundIn an ionic compound, the formula gives the ions and their ratios in the crystal lattice. In a molecular compound, the formula gives the numbers of atoms of each element in a molecule.
Roman numerals in a cation represent?
the number of electrons lost when forming an ion and that the cation can form more than one cation.
What is the atomic number of the cation formed in the reaction illustrated in Figure 2.3?
11. The atomic number refers to the number of protons in an atom, including a cation. In this case, the Sodium cation has 11 protons like the Sodium atom.
Name for PCl5?
Triphosphate Hexachloride
