dose 23 grams of sodium and 238 grams of uranium have equal number of atoms in them
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.
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.
The number of reactants atoms must be equal to the number of products atoms.
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.
The gas has molecules that are single atoms, as do the noble gases.
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.
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.
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).
no
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).
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.
Table salt is mainly sodium chloride - a compound with equal parts (in atoms or moles) of sodium and chlorine.
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.
Quite a few. 6.32 X 10^25 atoms sodium (1 mole Na/6.022 X 10^23) = 105 moles of sodium
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.
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.
Atoms of the same element usually have the same number of protons but differ slightly in the number of neutrons. The number of neutrons are usually about the number of protons so it can be estimated as so. For example, there are two relatively common isotopes of sodium: sodium 22 and sodium 23, where the number is the total number of protons and neutrons. Sodium 22 has 11 neutrons and sodium 23 has 12 neutrons but the sodium atom has 11 protons. For further information, look up isotopes.
