Differences: * All atoms are made up of neutrons, protons and electrons. Each element has a different number of protons, but the number of neutrons and electrons can vary. Typically, a hydrogen atom has one Proton, one electron and no neutrons. Oxygen atoms have 8 protons, 8 electrons and 8 neutrons. * Most commonly, Hydrogen atoms form +1 ions by loosing an electron. Oxygen forms a -2 ion, through the gaining of two electrons. (To understand why this is, you need to understand the electric charges of protons and electrons). These are the most basic differences. Similarities: * Both elements are quite volatile and will react with most other reactive elements. * They are both diatomic molecules. This means that they will always come in pairs such as H2 and O2, (two hydrogen or oxygen bonded together). There are other differences, but in much more complicated chemistry.

∙ 15y ago16 nucleons versus 1 , so about 16 times as dense, higher boiling point 8 protons versus 1, so 8 electrons versus 1, which means :- 2 electrons in the outer shell versus 1, different valency and different chemical properties.

What atoms is carbohydrates composed of?
Oxygen, hydrogen and carbons make up carbohydrates. In a chemical formula, it would look like C6H12O6 meaning there are 6 carbons, 12 hydrogens, and 6 oxygens. This makes the simple sugar, or monosaccharide. Different arrangements of these atoms make different types of sugar.
What does a molecule of H2O2 look like?
H2O2 or hydrogen peroxide has the two hydrogen atoms on either end of two bonded oxygen atoms. The hydrogen atoms are off at an angle in the same direction from the oxygen atoms ( non linear) and 110 degrees offset from each other. H-O-O-H
Are componds made of different combinations of atoms?
A compound is made when two ELEMENTS are joined together. We can look at the elements in the periodic table from these elements we get really everything that is around us. Water is a compound made from hydrogen and oxygen. There can be different combinations of the elements as this is what makes new things.
What are the properties of H2O?
Well It Stands For Every 2 Hydrogens, There is 1 Oxygen so That Is How Water Is Made :D Look: H = Hydrogen O = Oxygen 2 = 2 stands for every (_), There is (_) Amount of (_) It Is Very Useful If You Know The Periodic Table Because It Can Help!!! By The Way Do You Geddit???
A hydrogen bond is created between two molecules due to what?
When hydrogen is attached to a highly electronegative atom such as oxygen or nitrogen, the atom pulls the hydrogen's electron away from its nucleus causing the hydrogen atom to have a strong positive charge and the other atom to have a strong negative charge. Negatively charged atoms on other molecules are attracted to the strong positive charge of the hydrogen molecule (opposites attract), and the positively charged atoms are attracted to the negatively charged atoms.

How many atoms are in C4H12O6?
There are 24 atoms because C6 stands for 6 carbon atoms, H12 stands for 12 hydrogen atoms, and O6 stands for 6 oxygen atoms. C6H12O6 means Glucose, a.k.a "sugar for cells". If you want more details, you can look at the periodic table in Chemistry.
How manyAtoms in NO3?
Depends on how you look at it. There are a total of 4 atoms (1N and 3O) but there are only 2 different atoms (Nitrogen and Oxygen).
What atoms look like in liquid?
An atom is too tiny to be in a liquid . . . some atoms are the building blocks of liquids, though. For instance, the atoms of hydrogen and oxygen work together to form water, which can be a liquid.
What is H3PO4 and how many atoms present?
Phosphoric acid there is 3 hydrogen atoms 1 phosphorous and 4 oxygen the hydrogen has a charge of 1 and the phosphate (PO4) has a charge of 3- so it will look like H- PO4 3-
HOW many atoms in the water compound?
The number of atoms of oxygen in a compound depends completely on what the compound is. Some compounds, like water, have one oxygen atom. Some, like carbon dioxide, have two oxygen atoms. More complex compounds can have three, four, or even more oxygen atoms.
What look like in a liquid?
An atom is too tiny to be in a liquid . . . some atoms are the building blocks of liquids, though. For instance, the atoms of hydrogen and oxygen work together to form water, which can be a liquid.
Can one element be made up you many types of atoms?
no, one element is made up of entirely one type of atom for example if you take a look at hydrogen, this element is made up of entirely hydrogen atoms and therefore it is called hydrogen. if the hydrogen atoms mixed with lets say oxygen atoms, then this would be an example of a compound known as water. these elements are composed entirely of atoms with the same number of protons and when mixed with others form different compounds. The only differences that may exist beweeen atoms of the same elemnt are the number of neutrons in the nucleus, and the number of electrons. They will all have the same number of protons.
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 does a water molecule look like?
A water molecule is made of two hydrogen atoms and one oxygen atom. The hydrogen atoms are smaller than the oxygen atom. They are bonded together by covalent bonds in a 'bent' shape (like a shallow 'v') with the oxygen in the middle, at the point. The 'v' shape is because the oxygen atom has two pairs of unbonded electrons on, and they push the bonds further round the atom.
What causes the regions of charge polarity on water?
Water molecules contain two polar ends known as dipoles which are caused by the atoms that make up water. The chemical composition of water is H20 meaning that there are 2 hydrogen atoms bound to one oxygen atom. This bonding does not occur in a straight line and the bond angle between the 2 hydrogen atoms is 109 degrees and 27-28 minutes I believe. The hydrogen Atoms have a positive charge while the oxygen atoms have a negative charge which helps to hold the atom together (along with hydrogen bonding). If you look at a diagram of the structure of water, you will see that the hydrogen atoms are more on one side of the molecule while the oxygen is on the other. this makes one side slightly positive while the other side becomes slightly negative
