True, if it contains more than one is is not a single element but a combination of elements.
We should include one caveat: elements can have different isotopes of that element. By one definition all the isotopes are still the same "type" of atom since they all have the same number of protons even if they differ in the number of neutrons. If the number of protons differs you no longer have the same element.
True. An element is made up of one type of atom. This means that all atoms within a particular element have the same number of protons in their nuclei.
Elements that contain only one type of atom are called pure elements or monatomic elements. For example, helium (He), neon (Ne), and oxygen (O) are pure elements because they consist of only one type of atom in their chemical structure.
No. This is a definition of an atom. Electrons are only part of atoms.
Elements on the periodic table contain only one type of atom. Each element is defined by the number of protons in its nucleus, such as hydrogen (H) with one proton, helium (He) with two protons, and so on.
Hydrogen
An element. eg soduim: Na You can get diatomic and polyatomic ions/molecules like O2 and S8 which are normally gaseous. These contain only one kind of atom.
An atom of a chemical element contain only atom.
All elements in the Periodic Table contain only one type of atom.
Elements and atoms are related because elements contain only one type of atom.
Elements that contain only one type of atom are called pure elements or monatomic elements. For example, helium (He), neon (Ne), and oxygen (O) are pure elements because they consist of only one type of atom in their chemical structure.
An element contains no protiens. An element is made of only one type of atom. Protiens are made up of elements.
Copper is an element. An element consists of one type of atom. If there is more than one type of atom it can be a mixture of elements, or it could be a compound or alloy, but not an element.
There is no such thing as a cancer atom as cancer is not an element or even a substance. Cancer is a disease. An atom can belong to only one element and cannot contain others.
No. This is a definition of an atom. Electrons are only part of atoms.
Yes, atoms of any element contain only that element. It is impossible to have an impure atom.
False. A molecule is the smallest part of a compound that can still be indentified as a compound as it may contain several atoms of different elements. A single atom can only identify a single element, not a compound which it may have been a part of.
Elements on the periodic table contain only one type of atom. Each element is defined by the number of protons in its nucleus, such as hydrogen (H) with one proton, helium (He) with two protons, and so on.
