What is the approximate mass of a neutral atom with 31 electrons and 38 neutrons?
The mass of an atom is primarily determined by the protons and neutrons it contains since electrons have negligible mass. With 38 neutrons and an atomic number of 31 (which corresponds to the number of protons), this atom is likely a neutral atom of gallium. The approximate mass of this neutral atom can be calculated using the atomic mass of gallium (around 69.7 g/mol).
What best describes the nucleus of an atom?
It’s the most massive part of the atom
Fundamental unit of matter?
The fundamental unit of matter is an atom. Atoms are the building blocks of all elements and are composed of protons, neutrons, and electrons. They are extremely small, with a nucleus at their center surrounded by an electron cloud.
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.
An atom with more electrons would have charge?
An atom with more protons than electrons will have a positive charge. Neutral atoms can loose electrons if they are subjected to some kind of energy. Sometimed illumination with the correct color of light is sufficient to knock electrons off atoms.
Symbol for an atom of iron?
Iron's symbol is Fe.
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.
What does Fe mean in a chemical formula?
Fe is the chemical symbol for iron. In chemical formulas, Fe represents an atom of iron.
What is the oxidation number change for the iron atom in the reaction?
The oxidation number change for the iron atom in a reaction is from Fe^0 (elemental form) to Fe^2+ or Fe^3+ (ionic form). This represents an oxidation of the iron atom, as it loses electrons and increases its oxidation state.
What atom is Atomic number 26?
Fe Ferrum
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.
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.
Iron 3 hydroxide formula?
The formula for iron(III) hydroxide is Fe(OH)3. It consists of one iron atom (Fe) and three hydroxide ions (OH-).
What atom had 26 protons 26 electrons and 30 neutrons?
Iron-56 or 56Fe 56 protons makes it iron. If you add the protons and neutrons, you find the mass, which is 56.
What are oxidation numbers in the following compound fe2o3?
In Fe2O3, iron (Fe) has an oxidation number of +3, while oxygen (O) has an oxidation number of -2. This means that each Fe atom contributes +3 to the compound, and each O atom contributes -2.
What happened to the iron atom when chemical reaction occurred and an iron atom become the ion Fe?
Two or three electrons are lost.
