Does 23 g of sodium and 238 g of uranium have equal number of atoms in them?
dose 23 grams of sodium and 238 grams of uranium have equal number of atoms in them
Is uranium an isotope or neutral atom?
An atom has neutrons, protons, electrons. A chemical element has isotopes. With some exceptions isotopes has no name, but a number, equal to atomic mass.
How many total number of atoms are in NaCl?
The atomic number of Sodium (Na) is 11.The atomic number of Chlorine (Cl) is 17.There are one Sodium ion (Na+) and one Chloride ion (Cl-) in every Sodium Chloride (NaCl) molecule.
How do you calculate a balanced chemical equation?
The number of reactants atoms must be equal to the number of products atoms.
Do hydrogen and atoms have an equal number of electrons?
No. Neutral atoms of each element, including hydrogen, have a unique number of electrons, which is equal to the number of protons in their nuclei. The number of protons is the element's atomic number on the periodic table.

How many atoms in a mole of sodium?
A mole is a counting unit of molecules. Since sodium is an element and is exists by itself one mole of sodium will equal one mole of atoms or 6.02 x 1023 atoms.
Is uranium an isotope or neutral atom?
An atom has neutrons, protons, electrons. A chemical element has isotopes. With some exceptions isotopes has no name, but a number, equal to atomic mass.
What element has 11 protons 11 neutrons 11 electrons?
The neutral atom of sodium has 11 electrons. Sodium has eleven electrons in each of its atoms, as long as the atoms are neutral. You can determine this by looking at the atomic numbers on the periodic table. The atomic number is the number of protons in the nucleus of an atom. In a neutral atom, the number of electrons is equal to the number of protons. So, given the eleven electrons, you would look for the element with the atomic number eleven, which is sodium (Na).
Does the number of iron atoms in the reactants equal the number of iron atoms in the products?
no
What is the charge for uranium?
Protons = 92 Electrons = 92 Neutrons = 146 The number of electrons and protons in a neutral atom are each equal to the atomic number of the element (92). The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146).
What would 124 sodium atoms weigh?
Sodium has an atomic mass of 29.990 g/mol. This means that 124 sodium atoms have a mass of 3718.76 amu, if the isotopes follow the average. To find in grams, the following must be used: 124 sodium atoms equal 2.0598 * 10-22 moles, so 124 sodium atoms have a mass of 6.177 *10-21 grams.
What is table salt compound?
Table salt is mainly sodium chloride - a compound with equal parts (in atoms or moles) of sodium and chlorine.
How many total number of atoms are in NaCl?
The atomic number of Sodium (Na) is 11.The atomic number of Chlorine (Cl) is 17.There are one Sodium ion (Na+) and one Chloride ion (Cl-) in every Sodium Chloride (NaCl) molecule.
How many moles of sodium are equal to 6.32 x 1025 atoms?
Quite a few. 6.32 X 10^25 atoms sodium (1 mole Na/6.022 X 10^23) = 105 moles of sodium
How many atoms of hydrogen appear on each side of the equation?
The number of atoms in the reactants should equal the number of atoms in the products because the weight should be equal according to the Law of Conservation of Mass.
How many electrons are in an atom of elemental sodium equal to?
The number of electrons in a neutral atom is equal to the atomic number; sodium has 11 electrons. The number of protons is the same.
