How many electrons are in isotope U-238?
Isotope U-238 has 92 electrons. This number corresponds to the atomic number of uranium, which is 92.
How many electrons are there in a neutral atom of 238 over 92 U?
A neutral atom of (^{238}_{92}\text{U}) would have 92 electrons, as the atomic number (92) is equal to the number of protons (positively charged particles) and electrons (negatively charged particles) in a neutral atom.
How many electrons in U 238?
U-238 has 92 electrons. In the Periodic Table it is found at the bottom of the table, in the Actinides Period. Atomic No. 92 is U (Uranium) This number tells us that there are 92 protons and 92 electrons in an atom of uranium . The Atmoic Mass is 238 . This is made up of the total number of protons and neutrons in the nucleus of U . Hence the number of neutrons is 238 - 92 = 146. Uranium exhibits several isotopes. U-235 ; 92 protons , 92 electrons & 143 neutrons U-236 ; 92 protons, 92 electrons & 144 neutrons U-238 ; 92 protons, 92 electrons & 146 neutrons. Notice for all the isotopes of 'U' the number of protons and electrons remains the same at '92' each. It is the different number of neutrons that make for different isotopes. The name 'Uranium' comes from the planet 'Uranus' , which it turn comes from Classical Greek God, 'Uranus', the God of the sky. U
What does the number of valence electrons tell you about a given element?
If its positive it tells u that it has that number of valence electrons. If negative it tells you that it requires that number of electrons to make the valence electrons filled up/stable. If you know which Ion it is, you know the number of valence electrons of the neutral Atom. It corresponds to the group in the periodic table, the element is in. For example: Mg. It's in group 2, so it has 2 valence electrons. The oxidation number now tells you how many more or less electrons the atom has. For example: Mg(II) has 2 positive charges, hence two electrons less. That means it has 0 valence electrons. Take complete number of valence electrons, subtract the oxidation number and you get the number of valence electrons in the ion.
The number of valence electrons found in an atom of Group A element is equal to?
If by group A u mean Group 1, that would be one. Except for the transition metals, the # of valence electrons is equal to the one's place of the group #, except for helium because it can only have 2 and it is in the 8 group, but that is the group that has the most it can have.
How many electrons are in isotope U-238?
Isotope U-238 has 92 electrons. This number corresponds to the atomic number of uranium, which is 92.
In a reaction how many valence electrons will probably gain two electrons or share two covalent bonds?
In a reaction u need two valence electrons to gain or share two valence electrons.
How many electrons are in the isotope U-238?
Uranium is a chemical metal element. There are 92 electrons in a single atom.
How many electrons are there in a neutral atom of 238 over 92 U?
A neutral atom of (^{238}_{92}\text{U}) would have 92 electrons, as the atomic number (92) is equal to the number of protons (positively charged particles) and electrons (negatively charged particles) in a neutral atom.
