How many protons and neutrons are in phosphorous-32?
Well phosphorous always has 15 protons and even in different isotopes of an element the proton (atomic) number will be the same..So even in phosphorous-32, there are 15 protons.. If it is phosphorous-32 then the total of the protons and the neutrons is 32.. 15 protons...So to get the number of neutrons do 32 minus 15 = 7 neutrons.. Just to note, the number of electrons is of course the same as the number of protons so it is 15
Is it true that the periodic table is arranged by the number of neutrons?
No. For the most part, it is arranged by the number of protons. But even here there are exceptions.
Do atoms have equal electrons and protons?
Not all atoms have an equal number of protons and neutrons. They can, but they don't have to. Helium, for example, has two of each, but carbon (always with 6 protons) can have 6, 7, or even 8 neutrons. The more neutrons, the more likely it is to be radioactive. The number of protons and neutrons gives the atomic weight of an atom. All of the various amounts of neutrons that an element can have are called isotopes of that element.
If an atom has a mass of 23 amu does that mean it has an odd number of protons?
Not necessarily. The mass of an atom is determined by the sum of its protons and neutrons. An atom with a mass of 23 amu could have an even or odd number of protons, depending on the specific element.
How are electrons protons and neutrons positioned within an atom?
Electrons are on the outside rings of an atom. neutrons and protons are together in the nucleus of the atom. There is always the same number of protons and electrons in an atom, equal to the atomic number of the element. The amount of neutrons varies, even between atoms of the same number, these varieties of an element are called isotopes. If the amount of protons and electrons varies, it is called an ion, and the chemical number is still equal to the amount of protons.
Does alpha decay always decreases the number of protons by an even number?
Yes, an alpha radiation particle is 2 protons and 2 neutrons so for every alpha particle emitted the radioactive nuclide loses 2 protons.
Which isotopes have the same mass?
The number of protons and neutrons is what determines the mass of an isotope. Even though isotopes of a particular element have the same number of protons, but a different number of neutrons, which causes their mass to be different.
Does there have to be the same number of protons and neutrons in the nucleus?
No. Even atoms of the same element will vary in the number of neutrons in their nucleus. For example, carbon (6 protons) has isotopes with 6, 7, and 8 neutrons. The most common isotope of hydrogen (1 proton) does not have any neutrons. While the most common isotopes of the lighter elements generally have the same number of protons and neutrons, heavier elements will have more neutrons than protons. For example the most common most stable isotope of uranium (92 protons) has 146 neutrons.
How many neutrons are there in an element having a mass number of 52 and an atomic number of 22?
30. The Atomic mass is essentially the protons + neutrons. The Atomic number is the protons. Or the neutrons. Or even the electrons. With the exception of ions and isotopes, those numbers are all the same.
How do you use the symbol of an element to work out the number of protons neutrons and electrons in an atom?
The number of protons in an atom is equal to the atomic number, which corresponds to the position of the element in the periodic table. To find the number of neutrons, you subtract the atomic number from the atomic mass. The number of electrons is typically equal to the number of protons in a neutral atom.
How do you determine neutrons?
take nitrogen as an example it has an atomic number of 7 that determines the number of protons as 7 positive charges so it takes 7 negative charges (electrons) to even it out so you have 7 electrons and protons. then you take the atomic mass which is 14.01 but you can round it to 14. then you take the atomic number and atomic mass and subtract them (14-7=7) so the number of neutrons is 7.
If an atom has 15 protons 13 neutrons and 18 electrons what is the atom's electrical charge?
the nucleus always has a positive charge. The atom on the other hand in its singular state will have no charge as the electrons negative charge counter the protons positive charge. in this example there will be 31 electrons The element would be Gallium but there are not enough neutrons in your question to even make a viable isotope. Gallium typically has 31 protons and 39 neutrons
