What is the subscripts and superscripts of platinum 195?
The subscript of platinum-195 is 78, which represents the atomic number of platinum (the number of protons in its nucleus). The superscript is 195, which represents the mass number of the isotope (the total number of protons and neutrons in its nucleus).
What does a subscript tell us in a binary nonmetal compound?
In a binary nonmetal compound, a subscript tells us the ratio of atoms present in the compound. Each subscript represents the number of atoms of that element in the compound. For example, in CO2, the subscript 2 indicates that there are two oxygen atoms for each carbon atom.
What is the isotopic notation represents an atom of carbon-14?
The isotopic notation for carbon-14 is ^14_6C. This notation indicates the atomic number (6, which represents carbon) as a subscript and the mass number (14) as a superscript.
What do the superscript and subscript mean in the notation 40 K represent 19?
The subscript (19) indicates that this atom has 19 protons (as well as 19 electrons). The supersript (40) denotes that it has 40 protons and neutrons, hence we can infer that it has 21 neutrons.
What compound represents aluminum iodide?
It is AlI3. The character after the A is a lower case L, the next one is an upper case i and the final number should be in subscript.
What is the subscripts and superscripts of platinum 195?
The subscript of platinum-195 is 78, which represents the atomic number of platinum (the number of protons in its nucleus). The superscript is 195, which represents the mass number of the isotope (the total number of protons and neutrons in its nucleus).
What does a subscript in a chemical formula represents?
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
What is the difference between H and H subscript 2?
In chemical formulas, a subscript number signifies the number of atoms of the specified element in a molecule. For example, H2O (where the "2" is subscript) is the formula for water and represents 2 hydrogen atoms combined with 1 atom of oxygen.
What does the number represent in platinum-195?
It represents the atomic number and atomic mass. Mass number is the superscript Atomic number is the subscript
What is a number written to the right of a chemical symbol?
a subscript Number of atoms of that element in the molecule.
what number represents the subscript in the formula shown?
The letter or letters that represent an element are called its atomic symbol. The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
What does a subscript show in a chemical formula?
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
What type of number after a chemical symbol tells how many atoms of that elements in a single molecule?
The number after a chemical symbol in a chemical formula represents the number of atoms of that element in a single molecule. This number is called a subscript, and it indicates the ratio of atoms in the compound.
What is the subscript number for Plutonium?
If you think to the atomic number this is 94 for plutonium.
