If a single atom of a hunk of matter is still the same substance as the matter, then that matter is an element. (Gold, sodium, carbon, uranium, and so forth)
If the matter can only be broken down to a molecule, but not an atom, then it is not an element. (Salt, ammonia, sugar, alcohol, and so forth)
No, atoms are the smallest units of matter that retain the properties of an element. The properties of an element are determined by the number of protons in its nucleus, which defines its atomic number and unique characteristics. When atoms combine to form molecules, the properties may change due to new interactions.
All atoms of a single element have the same number of protons in their nuclei, which defines the element's atomic number. This characteristic gives each element its unique chemical properties. Additionally, while they may vary in the number of neutrons (resulting in different isotopes), the electron configuration, which determines how atoms interact with each other, is also consistent among atoms of the same element.
An element is a single kind of matter that is pure and has a specific set of properties. Each element is characterized by a unique number of protons in its nucleus, known as its atomic number, which determines its chemical behavior and physical properties.
a pure substance. :)
An element is a single kind of matter that cannot be broken down into simpler substances by chemical means. Each element is defined by its unique atomic number, which determines its specific properties and characteristics.
Every single atom of sodium has exactly 11 protons in the nucleus.
No, each element has a unique atomic number that corresponds to the number of protons in its nucleus. Changing the number of protons would change the element itself.
Boron is an element, not a compound. It is a chemical element with the symbol B and atomic number 5, characterized by its unique properties and behavior as a single element on the periodic table.
Technically no, since an element defines that it is a single atom. Tungsten Carbide is a chemical compound consisting of Tungsten and Carbon (W2C) and Graphite is a form of pure carbon
An atom is a simple form of matter that has unique chemical properties. Atoms are the basic building blocks of all substances and are made up of protons, neutrons, and electrons which determine their chemical behavior. Each atom has a specific number of protons in its nucleus, which defines its chemical identity.
it is called a pure substance
Atoms do have the same properties as long as stable form of its corresponding element is not a molecule. For example H1 (Hydrogen) which is a single atom has the same properties that of Hydrogen as it doesn't require to be in a molecular form to be stable. On the other hand O1 (Oxygen) doesn't have the same properties as Oxygen that we breathe as that Oxygen is actually O2 which is actually necessary for it to remain stable.
