Which symbol represents an atom with 9 protons and 10 electrons?
Which symbol represents an atom with 9 protons and 10 electrons?
Its atomic number, 9, indicates that there are 9 protons and 9 electrons in a neutral F atom. Use the equation E = P – C to calculate the number of electrons in an F- ion: E = 9 – (-1) = 10 electrons. So, an F – ion has 9 protons and 10 electrons.
What would be the isotope notation for a fluorine ion with 9 protons 10 neutrons and 10 electrons?
You would name this particular isotope using the mass number. It would be called fluorine-19. The nuclear or isotopic notation would be 199F .
What has 8 protons and 10 neutrons?
Fluorine
What has 8 protons and 9 Neutrons?
oxygen
Why does hydrogen have no neutron?
Hydrogen does not contain neutron, because its nucleus is smallest in size which cannot accommodate any heavier neutron. It also makes hydrogen atom unstable in nature.
Is there a neutron in a hydrogen atom?
Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. The isotopes of hydrogen have, respectively, mass numbers of one, two, and three. Their nuclear symbols are therefore 1H, 2H, and 3H. The atoms of these isotopes have one electron to balance the charge of the one proton.
Does hydrogen have a proton?
1
What happens when you add a neutron to a hydrogen atom?
Protons and electrons have equal and opposite charges while neutrons have no charge. If you add or subtract a proton from the nucleus, you create a new element. If you add or subtract a neutron from the nucleus, you create a new isotope of the same element you started with.
Can an atom lose protons?
The only two ways by which atoms lose protons is through radioactive decay and nuclear fission. Both processes will only occur in atoms that have unstable nuclei. It is well known that radioactively occurs naturally and spontaneously.
Do you add protons and neutrons?
Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom.
Can an atom lose a neutron?
Neutron emission is a mode of radioactive decay in which one or more neutrons are ejected from a nucleus. As only a neutron is lost by this process the number of protons remains unchanged, and an atom does not become an atom of a different element, but a different isotope of the same element.
Why can’t an atom gain a proton?
Why don t atoms gain or lose protons? Atoms never gain protons; they become positively charge only by losing electrons. A positive ion is called a cation (pronounced: CAT-eye-on). You may have notice that the number of neutrons in each of these ions was not specified.
Why can’t you add protons to make a positive ion?
If an atom develops a positive charge, how could it have happened? It couldn’t possibly have taken on additional protons because protons and neutrons are bound by the strong nuclear force, which keeps the nucleus stable.
What happens when you gain a proton?
Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom’s atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.
What would happen if carbon 12 gains a neutron?
If Carbon-12 were to gain a neutron its mass would be affected. It would still have 6 protons, but now it would have 7 neutrons. It would still be an isotope of Carbon. It would now be Carbon-13.
Can an atom lose electrons?
Sometimes atoms gain or lose electrons. The atom then loses or gains a “negative” charge. These atoms are then called ions. Positive Ion – Occurs when an atom loses an electron (negative charge) it has more protons than electrons.
Why can protons never change?
An elements atomic number will never change, that is because the atomic number is its “identity.” The atomic number is the number of protons that is contained in the nucleus, if you add a proton you change the element. Therefore, an elements atomic number will never change.
Why are even nuclei more stable?
Nuclides containing even numbers of both protons and neutrons are most stable and this means less radioactive. than nuclides containing even numbers of protons and odd numbers of neutrons. In general, nuclear stability is greater for nuclides containing even numbers of protons and neutrons or both.
Can oxygen decay?
Oxygen Isotopes While most oxgen atoms have a mass of 16 (8 protons and 8 neutrons), a small number of oxygen atoms have a mass of 18 (8 protons and 10 neutrons). Both of these isotopes are stable; they do not undergo radioactive decay.
