What does the number at the top of an carbon element tell you about it?

The number at the top of an element square is referred to as an atomic number. This number provides you with multiple information such as the number of protons and electrons the element has, and with the atomic number it is easier to locate the element on the Periodic Table. In this case, Carbon's atomic number would be 6, as well as how many protons and electrons are in its nucleus.

What is the element on top of the carbon group?
carbon alkali metal?
Does sodium have ten neutrons?
Actually, the element Sodium has eleven (11) electrons. You can tell by its Atomic number. (The number at the top left side of the element's box.)The Atomic number is both the element's proton and electron number.
What is the top number mean in each element?
The top number in each element means the number of protons and electrons in the atom of that element.
What atom has 6 protons?
On the periodic table, that would be considered as "Carbon". Just look at the atomic number at the top of the names on the periodic table, and that would give the numbers of protons in the atom.
If an atom six protons eight electrons and six neutrons what element is it?
The atomic mass is the number of protons, plus the number of neutrons. In this case, 8 + 6 = 14.Furthermore, the six protons (atomic number) tells me that this is carbon; the six electrons tell me that this is a carbon atom, rather than a carbon ion (an ion is when the number of electrons does not equal the number of protons, making the atom electrically non-neutral). The eight neutrons tell me that this is an isotope (in other words, a version) of carbon called carbon-14, which happens to be mildly radioactive; and therefore useful to archaeologists in dating human artifacts.
What is the number on top of an element called?
The Atomic Number
How can the number of core electrons be detemined from the periodic table?
Take carbon as an example.Carbon, indicated by it's atomic number, has 6 electrons. The number at the top of carbon's group is the number of valance electrons. Carbon has 4 valance elections.6 total electrons - 4 valance electrons= 2 core electrons in carbon=====================(try another element yourself to see this process )
The number of protons in an element is the?
The number of protons in an element is the atomic number, which can be found in the top right corner of the box containing the element.
How do you determine which element the atom belong to?
The number of valence electrons in an element is represented by the group number; for example, all elements in group one have one valence electron, all elements in group two have two valence electrons, etc.
Are protons the number on top or the bottom?
For a given isotope of an element, the "top number" (e.g. 14C or carbon-14) is the atomic mass number, the total of neutrons and protons. The bottom number, if displayed, is the atomic number (e.g. 6C all isotopes of carbon have 6 protons). To find the number of neutrons, subtract the atomic number from the isotopes atomic mass number. Here, 14C will have 8 neutrons, and the result is that it is an unstable radioactive isotope. Many stable elements, however, have many more neutrons than protons.
What are the top and bottom numbers of the isotopic notation for carbon 14?
The top number is 14 and the bottom number is 6. The latter is the same for any isotope of carbon, but the top number changes with the number of neutrons in the isotope, because the top number is the mass number, which is defined to be the sum of the numbers of protons and neutrons.
What number of protons in one atom of an element is that element's?
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
