The number of protons in the nuclei of their atoms. This is the atomic number of an element and each element has its own unique atomic number.
The atoms of each element have a number of protons that is unique to each element. The number of protons makes one atom different from another.
Elements are pure substances that cannot be broken down by chemical means. The atoms of each element have a number of protons that is unique to each element. The number of protons makes one atom different from another.
two or more different elements
atom and elements are different because one atom makes an element and a element is a pure substance and a atom is a basic particle
Atoms and elements can vary in many ways. Atoms mainly vary by having different numbers of protons, electrons, and neutrons. The count of protons makes up an elements mass number.
An element is a composition of many atoms. Thus you can hold NaCl (salt) in your hand. You can't hold the atoms it makes up.
their internal structure makes them behave in a similar way.
No, different samples of an element can have varying atomic masses due to the presence of isotopes. Isotopes are atoms of the same element with different numbers of neutrons, leading to different atomic masses.
The answer is that they make elements.
The atoms of each element have a number of protons that is unique to each element. The number of protons makes one atom different from another.
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.
Well the connection between atoms and elements is they are a compound... Usually compounds have quite different properties (e.g. colour, texture, taste, smell and density) from the elements whose atoms they contain... For example: the compound of water is a liquid at room temperature. Water contains atoms of the elements hydrogen and oxygen, which exist in air as colourless glass - quite different to water...
