What are the similarities and differences between atoms and molecules quizlet?
An atom is the smallest particle of matter and is made of protons, neutrons, and electrons. Molecules are made of two or more atoms combined together. You just studied 15 terms!
What are the similarities of atoms?
Similarities: both contain the same atoms, atoms in both contain 17 protons, both are neutral. Differences: one contains twice as many protons, neutrons and electrons as the other, one contains an unpaired electron, one is much more reactive than the other, one is described as a free radical.
What are similarities between atoms and compounds?
There are very few similarities between elements, compounds and mixtures. At the most basic level, all the three are composed of atoms. Elements and compounds are purely homogeneous substances and they have a constant composition throughout.
What is the similarities between atoms and elements?
A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.
What are the similarities between atoms and compounds?
On first glance, elements and compounds might appear different, yet they share many similarities, like being made up of atoms and having bonds linking their atoms together. Elements and compounds also share the qualities of being both pure and homogeneous substances.
What are the similarities and differences between an element and a compound?
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule.
How do atoms and molecules differ and compare?
Atoms comprise of the nucleus (which contains protons and neutrons) and electrons. Conversely, a molecule comprises of two or more, identical or different atoms, combined chemically. The shape of an atom is spherical whereas the molecules can be linear, angular or rectangular in shape.
Are atoms and molecules the same things?
The difference between atom and molecule is that an atom happens to be the smallest particle in any element and also possesses the properties of the element. Breaking down an atom any further and retaining the properties of the element is not at all possible. Molecules, on the other hand, are the result of the combined efforts of two or more atoms.
What is the weakest bond between two atoms or molecules?
Definition Hydrogen bonding is a weak type of force which forms a dipole-dipole interaction between two molecules within the same molecule. Depending upon different contexts, its definition has been changing.
Do molecules have to have at least two atoms?
Molecule is a substance with two or more atoms bonded together such as the oxygen humans breathe (O 2). Elements are pure substances made up of all the same atoms such as gold (Au), hydrogen (H), and oxygen (O). Elements all have the same number of protons in their nuclei and can’t be broken down.
