When an atom has an unbalanced ratio of protons and neutrons what will it try to do to stabalize itself?
There generally isn't a problem; the more protons an atom has, the more neutrons it takes to glue them together. A Helium atom has two protons and generally two neutrons; in every other stable atom, there are more neutrons than protons. There are isotopes of elements with fewer-than-normal numbers of neutrons; these isotopes are generally unstable and radioactive, and will generally decay into other elements.
How many protons neutrons and electrons does nitrogen have have?
According to Wikipedia neutral nitrogen has 7 protons, 7 neutrons, and 7 electrons. Nitrogen ions may have more or less electrons and other nitrogen isotopes may have more or fewer neutorns.
How many protons neutrons shells and electrons are in nickel?
The number of neutrons varies as there are isotopes to every element, meaning a different number of neutrons. The most common isotopes of nickel have 30 or 32 neutrons. All nickel atoms have 28 protons, and (if neutral) 28 electrons. Nickel ions will have fewer electrons depending on the charge. Neutrally charged nickel has 28 protons, 28 electrons and 31 neutrons
What is an isotope and why are atomic masses usually in decimal form?
An isotope is a variant of the atom with the same number of protons but more or fewer neutrons. The atomic mass is an average of the isotopes of the element. The average is weighted according to the relative abundance of such isotopes.
The total number of protons amd neutrons in the nucleus determines the atoms?
This is the "mass number" of the atom, indicating relative mass of an isotope.For example uranium-235 (235U) is a lighter atom than uranium-238 (238U) because while both isotopes have 92 protons (the atomic number), the first has 3 fewer neutrons.
How many neutrons in osmium?
The number of neutrons in the main isotopes of osmium and their abundance is116 (41%),114 (26%),113 (16%),112 (13%)There are three more isotopes with fewer protons and abundance below 5%.

How do two isotopes of an element similar?
Every element has a set number of protons. Always. Electrons are determined by the charge on the atom. If it is positive, it has fewer electrons than protons; if it is negative, it has more electrons than protons. Isotopes are atoms with different numbers of neutrons. So, neutral carbon-12 has 6 protons, 6 electrons, and 12 neutrons. Likewise, neutral carbon-14 has 6 protons, 6 electrons, and 14 neutrons. Carbon-12 and carbon-14 are isotopes
How much newtrons are in iron?
How many neutrons, not how much newtrons. Iron's atomic number is 26, so it has 26 protons; its atomic mass is approximately 56, which equals the number of protons and neutrons. 56 - 26 = 20 neutrons. While there are isotopes of iron with more or fewer neutrons, this is likely the answer you're expected to provide. If not, see Wikipedia "isotopes of iron".
12C has one fewer proton than 13C?
Carbon 12 and carbon 14 are atoms of carbon, different isotopes of the element. Carbon owes its chemical identity, indeed, its elemental identity, to the number of protons in its nucleus. There are 6 of them. No more, no less. Carbon 12 has 6 protons and 6 neutrons. Carbon 14 has 6 protons and 8 neutrons. Carbon 14 has fewer protons than neutrons.

How do two isotopes of an element are similar?
They have the same number of protons in the nucleus and same number of electrons surrounding the nucleus.
An atom with an imbalance of electrons and protons is called?
I'm not sure there's a word for it. Ones with fewer neutrons might be "neutron-deficient" (or "neutron poor"), though a) that's probably politically incorrect and b) I think it refers to nuclei that have less than the optimal number of neutrons, even if it isn't actually less than the number of protons.
What is an isotope and why are atomic masses usually in decimal form?
An isotope is a variant of the atom with the same number of protons but more or fewer neutrons. The atomic mass is an average of the isotopes of the element. The average is weighted according to the relative abundance of such isotopes.
How many protons electrons and neutrons are there in plutonium 240?
All the isotopes of plutonium has 94 protons and 94 electrons. For the number of neutrons of a specified isotope: number of neutrons = rounded atomic mass of the isotope - atomic number (or protons number) For plutonium-239: 94 protons, 94 electrons, 145 neutrons. The atomic number of plutonium is 94.
What is an atom with more or fewer neutrons than atoms of the same element?
An atom of a certain element with a different number of neutrons compared with the common form of the element is called an isotope. Isotopes have the same number of protons and electrons in an atom, but a different number of neutrons (which means that they have a different atomic mass number).
