The lower left number on a chemical symbol represents the atomic number of the element, which indicates the number of protons in the nucleus of an atom of that element. This number determines the element's identity and its position on the Periodic Table. For example, in the symbol for carbon (C), the atomic number is 6, meaning it has six protons.

What is uraniums symbol?
1. The chemical symbol of uranium is U. 2. For isotopes the mass and the atomic number are noted to left. Example for uranium 235: 92235U
What is the chemical symbol for an atom of oxygen?
The nuclide symbol for oxygen depends on which oxygen isotope is being referenced. Nuclide symbols consist of the number of protons and neutrons over the number of protons to the left of the atomic symbol. Thus, oxygen would have x/8 O.
What is a number written to the left of a formula called?
The number written to the left of a chemical formula is called a coefficient. It represents the ratio of moles of each substance in a chemical reaction.
What is a combination of element symbols that shows the ratio of elements in a compound?
It use the symbols as alphabetical characters for element names for examples: C for Carbon, Cu for copper (Cuprum in latin)And in the lower left of the symbol is atomic number, for C it is 6: 6Cin the upper left of the symbol is the mass number, for C it is 12 : 12C(or with another isotope, 13)Then the full nomination: 612C (write 6, and 12 one column aligned)(answer)My chemistry book states that its a Chemical Formula, "a shorthand representation of the composition of a substance using atomic symbols and numerical subscripts"
What indicates the number of protons?
The number of protons in an atom is indicated by the atomic number of the element. It is the whole number located above the element's symbol in the periodic table. The atomic number also determines the element's identity.
What is the symbol for promethium?

Where can you find atomic numbe rand atomic mass in the symbol of element?
The atomic number is usually written to the lower left of the atomic symbol. The atomic mass is usually written to the upper right of the atomic symbol. So, carbon-14 would look like this: 6C14
A number written to the left of a chemical symbol or formula is called?
The MOLAR RATIO or Coefficient. Do NOT confuse with numbers AFTER the chemical symbols. e.g. 2NaOH + H2SO4 = Na2SO4 + 2H2O The Molar Ratios (Coefficients) are in order from left to right ' 2:1 :: 1:2 '. In Na2SO4 the numbers '2' refers to TWO sodium atoms And '4' refers to FOUR oxygen atoms. In '2H2O'. The left hand '2' refers to TWO molar ratios. The '2' to the right of 'H' (Hydrogen) refers to each molecule having two (2) hydrogen atoms. NB When no number is shown, read it as '1'(one). This applies to molar ratios and to atom numbers in a molecule. e.g. NaOH ; No numbers, so there is only ONE of each atom. Similarly, H2O means only ONE(1) atom of oxygen, in the molecule.
What is the chemical equation of technetium 99?
Technetium-99 has not a chemical equation but an isotopic symbol. This is Tc with:- to the left, as a superscript, 99- to the left as a subscript, 43
What do the 2 numbers in atoms mean?
the number which is written on the lower left or right side of the symbol of the element = mass number = no. of protons + no. of neutrons the number which is written on the upper left side of the symbol of the element = atomic number = no. of protons = no. of electrons (because in a neutral atom i.e. which does not have any charge , no. of electrons = no. of protons) and PLEASE KEEP YOUR QUESTIONS IN THE PROPER CATEGORY
What are three names of isotopes of promethium?
Isotopes of promethium haven't special names. Promethium has 38 isotopes and isomers, all radioactive.Isotopes of all elements contain the chemical symbol of the element and:- as a superscript, to left: the mass number of the isotope- as a subscript, to left: the atomic number of the elementA correct symbol is not possible to be written on WikiAnswers window.
What is the symbol in the lower left corner on the right side of the rmp symbol?
The symbol in the lower left corner, typically found in conjunction with the RMP (Risk Management Plan) symbol, often represents a specific hazard or risk type, such as a chemical or biological hazard. It serves to alert users to particular risks associated with the materials or processes covered in the RMP. The exact meaning can vary depending on the context and the regulatory framework in which the symbols are used. For precise identification, it's best to refer to the accompanying documentation or key that explains the symbols used.
What does the greater than or equal to symbol mean?
The greater than or equal to symbol is put between two numbers, where the number on the left of the symbol is "greater than or equal to" the number on the right. That just means the number to the left is either bigger than the number on the right or it's equal to, or the same as, the number to the right. This is mostly used when you don't know exactly what the number on the left is, but you know it's larger or equal to the number on the left.
How do you draw an atomic number for silver?
The atomic number for silver is 47, which means it has 47 protons in its nucleus. To draw a simple representation, you can write "Ag" (the chemical symbol for silver) and place the atomic number (47) as a subscript to the left of the symbol.
What is the chemical symbol for an atom of oxygen?
The nuclide symbol for oxygen depends on which oxygen isotope is being referenced. Nuclide symbols consist of the number of protons and neutrons over the number of protons to the left of the atomic symbol. Thus, oxygen would have x/8 O.
