How many sodium atoms (Na) are there?
1, because Na does not have a number after it.
What changes in atomic number and mass number occur in beta emission?
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
What is the atomic number of Na 23?
atomic weight - protons = neutrons, Na-23 has an atomic weight of 23 amu, and 11 protons so 23-11=12 neutrons
What is the atomic number hydrogen?
Hydrogen is a gas. atomic number of H is 1.
Is hydrogens atomic number 1.008?

What are the atomic numbers of the first three elements in Group 1?
1 H Hydrogen3 Li Lithium11 Na Sodium
The symbol for the chemical element hydrogen is H and its atomic number is 1 what is the symbol and atomic number for the element sodium?
Sodium symbol: Na Atomic number: 11
Hydrogen plus atomic number?
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.
What is the atomic number of He plus?
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.
What information about electrons does the periodic table give?
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)
How many sodium atoms (Na) are there?
1, because Na does not have a number after it.
What is the oxidation number of Na in N2SO4?
+1 for Na, +1 for H, -2 for each O, +4 for S
Atomic number of Na?
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.
What happens to the atomic number when the nucleus releases a beta particle?
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.
Atomic number of sodium?
It weighs the same as the atomic weight of a bannana
How is atomic number differ from mass number?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
