What is the approximate mass of a neutral atom with 31 electrons and 38 neutrons?
From the periodic table, the atomic number of iron (Fe) is 26. This means that iron atoms have 26 protons in their nuclei. Mass number is the number of protons and neutrons in the nucleus of an isotope of an element. So, for your example of 31 neutrons, the sum of the number of protons (26) and neutrons (31) is 57. So the mass number of this iron atom is 57.
What best describes the nucleus of an atom?
It’s the most massive part of the atom
Fundamental unit of matter?
A cell is a basic unit of structure. The smallest unit of matter is an atom.
How does an atom becomes Negatively charged?
An atom becomes negatively charged when it receives an electron from another atom. In other words, if there are more electrons than protons in an atom, it becomes negatively charged.
What is an atom stable?
An atom is stable if it does not undergo decay.
During a chemical reaction an iron atom became the ion Fe 2 plus . What happened to the iron atom?
If Fe becomes Fe^2+ it has lost 2 electrons, and so the Fe has been OXIDIZED.
An atom of this element has 10 more protons than an atom of sulfur?
Iron, Fe
What atom is Atomic number 26?
Fe Ferrum
Symbol for an atom of iron?
Iron's symbol is Fe.
What is the example of element with the symbol for a single atom of the at element?
Take the element "Iron" then the symbol for the element is "Fe" and "Fe" is also the symbol for a single atom of the element in a chemical equation.
How many atoms are in Fe?
Two atoms in 2 atoms of Fe (this dose not make sense pleas edit)
What is Fe and Fe2o3 in terms of chemistry?
The first Fe represents an iron atom in the 0 oxidation state while the Fe in Fe2O3 represents iron ion in the +2 oxidation state
What is the number of protons in Fe 3 plus?
There are similar number of protons in the ion and the atom. Fe+3 ion contains 26 protons.
What happened to the iron atom when chemical reaction occurred and an iron atom become the ion Fe?
Two or three electrons are lost.
What does the element description “iron-57” actually mean?
It means that the atom being discussed is an isotope of iron that has a mass number of 57, which means that the atom has 31 neutrons.Added:It is the 3rd most abundant Fe isotope after Fe-56 and -54.
What is the difference of ion and molecule?
An ion is an electrically charged atom, charged due to the gain or loss of an electron, such as Fe++ (a cation, because the Fe atom has gained two electrons) or Cl- (an anion, because the Cl atom has lost an electron). A molecule is a complex structure made up of more than 1 atom. They can be made from the same atom (like a molecule of oxygen, O2) or different atoms (like H2SO4).
In a chemical reaction an iron atom became the ion Fe2 plus . What happened to the iron atom?
The iron atom loses two(2) electrons to be come the Iron ION. Fe = Fe^(2+) + 2e^- NB An atom , when it becomes a charged spacied , is no longer an atom , but an ION. Positively charged ions are CATIONS Negatively charged ions are ANIONS.
