What Atomic Number represents?
The atomic number equals the number of protons in an atom, as well as the number of electrons in a stable, electrically neutral atom, it represents the identity of an element ,the simplest form of matter.
What makes an atom neutral?
An atom is neutral if the numbers of protons and electrons are equal it's neutral.
What is a neutral stable atom with a mass of 8?
The mass number is the number of protons and neutrons added together. Electrons are not counted as part of the mass because while protons and neutrons weigh the same, Electrons weigh virtually nothing compared to them. As far as I can tell, there is no stable atom with a mass of 8.
How many protons would you expect to find in neutral nitrogen atom?
A neutral nitrogen atom has 7 protons. This is because nitrogen has an atomic number of 7 and each atom has the same number of protons as its atomic number. Therefore a neutral nitrogen atom would have 7 protons.
An atom has the same number of which two particles?
A neutral (uncharged) atom has the same number of protons and electrons. Isotopes of an element may have several stable isotopes with various numbers of neutrons.
If an atom were to have two protons then it would?
It would by definition be Helium (atom number = number of protons = 2) but the nucleus of the stable isotope 4He also contains 2 neutrons (the mass number = total number of p's and n's = 4)
How do you determine the number of electrons that an atom normally have?
by the atomic number which determines the number of protons. a stable atom will have an equal number of electrons as protons. if there are more or less, it is an ion
If an atom has two protons would it be stable?
The atoms having 2 protons only in nucleus is not stable but 2 protons with 2 neutron in Helium nucleus are very stable.
What Atomic Number represents?
The atomic number equals the number of protons in an atom, as well as the number of electrons in a stable, electrically neutral atom, it represents the identity of an element ,the simplest form of matter.
How do you determine the number of protons in an atom of aluminum27?
There are 13 protons in an atom of aluminum, regardless of the isotope. If it didn't have 13 protons, it wouldn't be aluminum, it would be something else. There are 14 neutrons in an atom of aluminum 27, its only stable isotope.See the Related Questions for how to count the number of protons, neutrons and electrons in any atom of any element.
What makes an atom neutral?
An atom is neutral if the numbers of protons and electrons are equal it's neutral.
An equal number of protons and neutrons typically results in an atom that is?
Often, but not always, atoms with an equal number of protons and neutrons in the nucleus are stable and not radioactive.
Why must the number of protons and atoms in an element be the same?
If you mean protons and electrons then protons are positive and electrons are negative, so the protons and electrons cancel each other out leaving the atom stable. If the numbers were uneven, the atom would be unstable and decay, but that doesn't mean that all unstable atoms have an uneven number of protons and electrons.
What is a neutral stable atom with a mass of 8?
The mass number is the number of protons and neutrons added together. Electrons are not counted as part of the mass because while protons and neutrons weigh the same, Electrons weigh virtually nothing compared to them. As far as I can tell, there is no stable atom with a mass of 8.
What does the atomic number have to do with a element?
The atomic number represents the number of protons in the nucleus of the given atom. Also, it provides the number of electrons to keep the atom stable (neutral).
How would you figure the number of protons or electrons in an atom?
The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.
How is an atoms atomic number related to it's number of protons to electrons?
The atomic number of an atom is the number of protons in the nucleus of that atom. The number of electrons will equal the number of protons in that atom if that atom is a neutral one. Other than that, we would have to know the atomic number (which is the number of protons that atom has), and the overall charge of the atom. With that information, we could discover how many electrons that atom had by simple mathematics. If an atom had 11 protons and a charge of +1, it would have one less electron than the number of protons, or 10 electrons. If an atom had 53 protons and a charge of -1, it would have 54 electrons. The ratio from atomic number to the number of protons in an atom is 1:1. The elements are categorized by the number of protons they have, as that is the difference between two elements. Conceptually, atomic number and proton number are the same.
