How many neutral atoms does sodium have?
11
The mass number is given at the top left of the elements symbol, for example, sodium has a mass number of 23. We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons.
What do all sodium isotopes have in common?
Sodium has one naturally occurring isotope. The nucleus of this isotope contains 11 protons and 12 neutrons and is not radioactive. There are 18 other known isotopes of sodium. All are radioactive.
What does the neutral atoms of all of the isotopes of the same element have?
Neutral atoms have the same number of electrons and protons. Each isotope of a given element has the same atomic number but a different mass number (A), which is the sum of the numbers of protons and neutrons.
How many electrons does a neutral atom of sodium?
11 electrons
A neutral sodium atom, for example, contains 11 protons and 11 electrons.
How many protons does sodium have?
Sodium/Atomic number
What do all sodium isotopes have in common that distinguishes them from other isotopes?
How is atomic mass calculated? What do all sodium isotopes have in common that distinguishes them from atoms and isotopes of other elements? all have same number of protons. What are the electrons, protons, and nucleus located in an atom?
How many isotopes does sodium have?

Are all neutral atoms of the same element the same?
Each atom of an element contains the same number of protons, which is the atomic number (Z). Neutral atoms have the same number of electrons and protons. Each isotope of a given element has the same atomic number but a different mass number (A), which is the sum of the numbers of protons and neutrons.
Do isotopes react the same as neutral atoms?
While isotopes has different numbers of neutrons, massive, neutrally charged, nuclear particles, they have the same number of protons, massive, positively charged, nuclear particles. And if there is the same number of electrons, the chemistry of that element is essentially the same.
What is a neutral atom?
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.
What are all atoms neutral?
Atoms are neutral if they have the same number of charged protons and electrons, balancing positive and negative charges. As long as the numbers of electron and protons are the same, the charges will balance. Sometimes atoms are more stable though when they are not perfectly electrically neutral.
How many protons and electrons are in a neutral atom of sodium?
, physicist unhinged. Sodium has 21 known isotopes. All of those isotopes would have 11 protons per sodium nucleus, and 11 electrons, in the neutral atom.
What are the mass numbers of Typical isotopes of sodium?
Mass numbers of typical isotopes of Sodium are 23. Its only stable isotope is 23 Na. Two radioactive, cosmogenic isotopes are the byproduct of cosmic ray spallation: 22Na has a half-life of 2.6 years and 24Na, a half-life of 15 hours; all other isotopes have a half-life of less than one minute.
Do all isotopes have the same number of protons and electrons?
All isotopes of an element have the same number of protons and electrons, which means they exhibit the same chemistry. The isotopes of an element differ only in their atomic mass, which is given by the mass number (A), the sum of the numbers of protons and neutrons.
How many isomers of sodium are there?
Na and two isomers ( 22m. Na and 24m. Na ). 23. Na is the only stable (and the only primordial) isotope. It is considered a monoisotopic element and it has a standard atomic weight of 22.989 769 28(2). Sodium has two radioactive cosmogenic isotopes ( 22. Na, half-life = 2.605 years; and 24.
