1, because Na does not have a number after it.
Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2
atomic weight - protons = neutrons, Na-23 has an atomic weight of 23 amu, and 11 protons so 23-11=12 neutrons
The atomic number of hydrogen is 1. It is the first element on the periodic table, symbolized as H.
Sodium typically forms a +1 charge when it becomes an ion by losing one electron.
The atomic numbers of the first three elements in Group 1 are: Hydrogen (H) - atomic number 1 Lithium (Li) - atomic number 3 Sodium (Na) - atomic number 11
Sodium symbol: Na Atomic number: 11
Hydrogen has an atomic number of 1, which means it has 1 proton in its nucleus. This is the defining characteristic of hydrogen as an element.
The atomic number of helium (He) is 2. When He gains one electron to become He plus, it becomes an ion with a net charge of +1, but the atomic number remains the same as 2.
The atomic number (Z) gives the number of protons in the atom. For a neutral atom, this is equal to the number of electrons. For an ion, plus or minus the number given by the charge. i.e. sodium has atomic number 11, so Na would have 11 electrons and Na+ would have 10 electrons (each electron is -1 remember)
1, because Na does not have a number after it.
The oxidation number of Na in N2SO4 is +1 because in most compounds, the oxidation number of Na is +1.
That depends on the molarity of Na you have. 1 atom of Na consists of one sodium atom. One mole of Na consists of 6.02214 x 1023 atoms of Na.
When the nucleus releases a beta minus particle the atomic number increase with 1.When the nucleus releases a beta plus particle the atomic number decrease with 1.
The atomic number of sodium is 11. This means that sodium has 11 protons in its nucleus.
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
Silver is a metal element. Atomic mass number of it is 197.
