List the nameof each element that appears in the formula and give the number of atoms of each element present. HOOCC6H4OOCCH3?
Hydrogen - 8 Oxygen - 4 Carbon - 9 So, shorthand formula is C9H8O4 = aspirin
Atoms that are the same kind is called?
Isotopes - atoms with the same atomic number, number of protons and number of electrons
Gold is made out of what?
Gold is an element, so it's made out of gold atoms. it has atoms icons
How do chemical bonds hold elements?
Each atom is an element according to its atomic number. Meaning the isotope and number of protons in an atom. A chemical bond is an attraction of atoms to each other, so basically it is attracting different elements.
How many types of atoms can be found in a in a single element?
A pure element contains one sort of atoms, and all the elements have the same number of protons (which define the element). But the atoms can have different masses, so called "isotopes" (see link). Thus, chemically there is only one kind of atoms in a pure element, but there can be several physically different kinds of nuclei in a pure element.
How do atoms define or determine elements?
Each element is different so for a certain element to be define/determined it has different atoms to make it up so no other element has the same atoms
How is atomic number used to tell one element from another?
The atomic number of an element stands for the number of protons in the unique atom of the element. The atomic number also is the same as the number of electrons. The atoms in each element differ from atoms in other elements by virtue of the number of positively charged protons in the atomic nucleus and the corresponding number of negatively charged electrons. The number of protons (or electrons) is the atomic number of the element. The atomic number ranges from 1 for Hydrogen to 92 for Uranium and then beyond through the transuranic elements created in laboratory conditions.

How do you determine the number of atoms and elements in a chemical form?
Look at the subscripted number to the right each element's symbol. That is how many atoms of that element are in one formula unit. If no number appears next to the chemical symbol, then the number of atoms is 1. The total number of atoms is the sum of the number of atoms of each element. For example, the formula for sulfuric acid is H2SO4, a compound of the three elements hydrogen (H), sulfur (S), and Oxygen (O). Hydrogen's subscript is 2, oxygen's is 4, and Sulfur does not have a subscript. So 1 molecule of sulfuric acid contains 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms, for a total of 7.
How can the number of atoms of an individual element be determined by using a chemical formula?
The subscript number after the element symbol, such as the 2 in H2O, tells how many atoms in each molecule. In the example, the 2 refers to H (hydrogen). If there is no number present, then 1 is implied. So H2O has 2 hydrogen and 1 oxygen.
What is molecular formulae?
The molecular formula of a compound is the number of atoms of each element in one molecule. So in water (H2O), one molecule of water has 2 Hydrogen atoms and one oxygen.
Are all atoms of a given element identical to one another and different from atoms of other elements?
No. Some may have different numbers of neutrons. Atoms of the same element (atoms with the same number of protons in the nucleus) may have different numbers of neutrons, and so will have different masses. As an example, chlorine is a mixture of different isotopes with some of the atoms having different neutrons numbers.

How are all F atoms different from each other?
They are not! The whole point about atoms of an individual element is that they are all essentially the same. There may be a small number of varieties - isotope - in which the number of neutrons varies, but that is the only difference.

Gold is an element, so it's made out of gold atoms. it has atoms icons

How many different types of atoms are in helium?
Helium is an element, so it is made of only one type of atom.
