Which symbols represent atoms of the same element that are istopes?

The normal chemical symbol is used for the isotope with the addition of the atomic number (Z) at the lower left of the symbol and the Atomic Mass number (A) at the upper left as shown X.
For example Li and Li represent two isotopes of lithium.
Since all lithium isotopes have an atomic number Z=3, this number is usually omitted and the isotopes are represented by the symbols Li and Li. These are sometimes written as Lithium-6 and Lithium-7 or Li-6 and Li-7.

What are isotopes easy definition?
Istopes: Atoms of the same element that have the same number of protons but a different amount of neutrons.
Why is it useful to have symbols for atoms of different element?
atoms have symbols so that the atoms of different elements can be distinguished easily.
Why do scientists use symbols to represent atoms?
Symbols are universally understood across many languages. Also, using symbols rather than full names helps scientists to avoid the repetition of writing the long names of elements and atoms again and again.
What type of number after a chemical symbols tells how many atoms of that element are in single molecules?
That would be subscript.
How many total atoms are in the element 2c6h8o7?
First, 2C6H8O7 is NOT an element it is a Compound. Second the formula for the compound TELLS you how many atoms are present! 2C6H8O7 = Ignoring the element symbols is 2*(6+8+7) 2*(6+8+7)= 2*(21) = 42 Atoms

What are isotopes easy definition?
Istopes: Atoms of the same element that have the same number of protons but a different amount of neutrons.
How does the chemical formula of a compound relate to the relative number of atoms in the compound?
Chemical formulas consist of chemical symbols and numbers. The symbols represent the elements in the compound. The numbers indicate the quantity of atoms of each element in the compound.
Why is it useful to have symbols for atoms of different element?
atoms have symbols so that the atoms of different elements can be distinguished easily.
What are Atoms of the same substance that have different number of neutrons?
istopes
What do atoms represent?
to what number the element can count to
What do chemist use to stand for atoms or elements?
Atomic symbols are used to represent elements, a negative (-) and a psoitive (+) represent electrons and protons, respectively. Chemicals or other compounds are often written as a combination of atomic symbols with subscripts to indicate the presence of multiple atoms.
Are all atoms of the same element chemically alike?
Not 100%; Istopes of an element do have identical electronic structures but there are slight differences in mass: 'Molecules with different isotopes of a particular element have different bonding characteristics: the bonds between the atoms are just a bit different because the atoms have different masses. As a result, the molecules with different isotopes behave a little bit different during chemical reactions.' See related link
What do the periodic table symbols mean?
A typical periodic table has the element symbol e.g. C for carbon, W for tungsten, Pb for lead etc and often has the atomic number of the element (atomic number is the number of protons in the nucleus and therefore the number of electrons in a (neutral) metal atom.
Are atoms in a chemical change irregular?
No, the atoms in a chemical change are normal atoms of the element they represent. The atoms in the reactants are exactly the same atoms in the products, just arranged in a different way.
Why do scientists use symbols to represent atoms?
Symbols are universally understood across many languages. Also, using symbols rather than full names helps scientists to avoid the repetition of writing the long names of elements and atoms again and again.
