are atoms or groups of atoms that have?

Ion – an atom or groups of atoms that has a positive or negative charge. Cation – An ion with a positive charge. Anion – An ion with a negative charge. Chemical Formula – Notation that shows what elements a compound contains and the ratio of the atoms of ions of these elements in the compound.

Only if the number of protons (and consequently the electrons) is different, the atoms are of two different elements. The number of neutrons in atoms of different elements can be the same and so can the number of neutrons in two atoms of the same element be different.

The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element. We refer to the atoms of the same element with different numbers of neutrons as "isotopes".

An atom is an element. The two words are synonymous, so if you're looking for the number of atoms in an element, the answer is always one, and only one.

How do atoms exist? Atoms of most elements are not able to exist independently. Atoms form molecules and ions.
640435
Atoms are composed of three main subatomic particles: protons, neutrons, and electrons. Protons and neutrons are grouped together in the nucleus of an atom, while electrons orbit about the nucleus.

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. ... All known elements are arranged on a chart called the Periodic Table of Elements.

Yes, all things are made of atoms, and all atoms are made of the same three basic particles - protons, neutrons, and electrons. But, all atoms are not the same. You know that the number of protons in an atom determines what element you have. ... They are the glue that holds atoms together in chemical bonds.
595044
Atoms of different elements can combine to make new substances. A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound. All compounds are molecules, but not all molecules are compounds.
400541
An atom is the smallest amount you can have of an element whereas a molecule is the smallest amount you can have of a compound. A compound is made of atoms.

Yes, all things are made of atoms, and all atoms are made of the same three basic particles - protons, neutrons, and electrons. But, all atoms are not the same. You know that the number of protons in an atom determines what element you have. For instance hydrogen has one proton, carbon has six.

There's more to the atom than the electrons. ... The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element. We refer to the atoms of the same element with different numbers of neutrons as "isotopes".

The atoms of element differ from each other based on the number of protons or electrons they have. The number of protons or electrons is called the atomic number of an element which serves as its original identity.

Atoms are the smallest and most basic units of matter that have the properties of an element. All atoms have the same basic parts (electrons, protons, and neutrons), but they are arranged in different ways.
36432
Atoms of the same element (i.e., atoms with the same number of protons) with different numbers of neutrons are called isotopes. Most naturally occurring elements exist as isotopes. For example, most hydrogen atoms have a single proton in their nucleus.

The atom is the smallest unit of an element. Molecules, mixtures, and compounds can be broken down into smaller constituents with relative ease. Which of the following is NOT a substance made of one type of molecule. A cell is a collection of many different types of molecules.
327300
An atom is the smallest particle of an element that still has elemental properties. Atoms are made up of similar properties called protons, neutrons, and electrons. The smaller electrons orbit around a central nucleus of protons and neutrons. Atomic number. The number of protons in the nucleus of an atom.
