how many types of atoms can be found in a single element?
532978
There are more than 109 different types of atom - one for each element. Differences between the atoms give the elements their different chemical properties.
1054725
An atom is the smallest unit of matter that retains all of the chemical properties of an element. ... Most atoms contain all three of these types of subatomic particles—protons, electrons, and neutrons.
1246284
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.
133377
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. ... A compound is a substance made from two or more different elements that have been chemically joined.

Within each shell of an atom there are some combinations of orbitals. In the n=1 shell you only find s orbitals, in the n=2 shell, you have s and p orbitals, in the n=3 shell, you have s, p and d orbitals and in the n=4 up shells you find all four types of orbitals.

The structure of the atom. An atom is the smallest unit of matter that retains all of the chemical properties of an element. ... Most atoms contain all three of these types of subatomic particles—protons, electrons, and neutrons.

Although more than 25 types of elements can be found in biomolecules, six elements are most common. These are called the CHNOPS elements; the letters stand for the chemical abbreviations of carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur.
409223
Elements are atoms all of the same atomic number, i.e. all atoms of an element have the same number of protons in their nucleus. Substances can be elements but they can also be molecules. ... Substances, loosely defined as the word is, could also be compounds, which can include different kinds of molecules.
428320
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. ... Because different isotopes have different numbers of neutrons, they do not all weigh the same or have the same mass.

Elements are pure substances which are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are united chemically in fixed proportions. There are nearly 118 elements (at present) of which nearly 94 occur naturally on Earth.
618102
Since 2016, the periodic table has 118 confirmed elements, from element 1 (hydrogen) to 118 (oganesson). Elements 113, 115, 117 and 118, the most recent discoveries, were officially confirmed by the International Union of Pure and Applied Chemistry (IUPAC) in December 2015.
551430
There are more than 109 different types of atom - one for each element. Differences between the atoms give the elements their different chemical properties. In 2001, there were 115 known elements.
641034
The atoms of different elements have different numbers of electrons, protons, and neutrons. Every element is unique and has an atomic number. That number tells you the number of protons in every atom of the element. The atomic number is also called the proton number.
124870
Protons, neutrons, and electrons are the three main subatomic particles found in an atom. The element Na has 11 protons, 11 electrons, and 12 neutrons for a total of 34 subatomic particles.
986333
Answer and Explanation: There are 10 3d electrons in an atom of each element. This is true for elements which have filled 3d shells such as gold.
496843
The number of protons in the nucleus of an atom determines an element's atomic number. ... For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1. All carbon atoms, and only carbon atoms, contain six protons and have an atomic number of 6.

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.
