its nucleus.
This is an example of a chemical change. When an atom loses an electron to another atom, it undergoes a chemical reaction, resulting in the formation of new chemical compounds with different properties.
The smallest part of an element that has the properties of that element is the atom.
An atom's physical properties are mainly determined by its atomic number, which dictates the number of protons in its nucleus and therefore its overall charge. The arrangement of electrons around the nucleus also plays a key role in determining an atom's physical properties, such as its size, reactivity, and ability to form chemical bonds. Additionally, the specific elements present in an atom, as well as its isotopic composition, can influence its physical properties.
It is an atom.
The atom or smaller, the amount of protons like helium always has 2 protons no matter what.
The smallest part of an element that retains all its properties is an atom. Each atom is made up of protons, neutrons, and electrons that determine the chemical behavior and physical properties of the element.
An element's atomic number is equal to the amount of electrons or protons in an atom of that element. When an atomic number increases or decreases, the amount of electrons is changing.
because when mass number will change then the whole atom will change.
It is the distribution of electrons of an atom in different shells. It helps to understand various physical and chemical properties of an element.
Displacing hydrogen from an atom is a chemical property, as it involves a chemical reaction that results in a change in the substance's composition and properties. Physical properties, on the other hand, are those that can be observed or measured without changing the substance's chemical composition.
The particle in an atom that cannot change is the number of protons. If that changes, it is no longer the same element.
No, the combination of a carbon atom with two oxygen atoms to form carbon dioxide is a chemical change because the atoms are rearranging to form a new substance with different properties.
