What else can I help you with?
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.
What is the part of the atom that includes protons neutrons and electrons?
Neutrons are part of the nucleus itself, and electrons circle the nucleus
Which particles that make up an atom are involved in nuclear reactions?
Protons, electrons, and neutrons are the subatomic particles that are involved in nuclear reactions.
If the number of protons exceeds the number of neutrons is the charge on the atom positive or negative?
If the number of protons exceeds the number of neutrons, the atom itself is neutral in charge because protons are positively charged and neutrons are neutral. However, if you're referring to charged particles, an excess of protons (compared to electrons) would result in a positive charge for the atom, making it a cation. In summary, an atom's charge is determined by the balance between protons and electrons, not neutrons.
Is the number of protons equal to the atomic mass minus the atomic number?
No, the number of protons is equal to the atomic number, which is also the same as the number of electrons in a neutral atom. The atomic mass, on the other hand, is the sum of the protons and neutrons in an atom's nucleus.

How many neutrons does the neutral atom have?
It varies depending on the atom but basically there are the same number of neutrons as there are protons. Helium has two protons, two electrons, and two neutrons. The difference between the atomic mass and the atomic number equals the atom's number of neutrons. Consider hydrogen, for example. Standard hydrogen has no neutrons, just one proton. Deuterium is an isotope of hydrogen with one neutron, and tritium (which is unstable) has two neutrons. Carbon 12 has six protons and six neutrons, but carbon 14 (which is unstable) has six protons and eight neutrons. As you move up the periodic table, nuclei tend to have more neutrons than protons. 92 U 238, for example, has 146 neutrons.
What are located at an atoms nucleus?
Protons and neutrons are located at an atom's nucleus. These particles are responsible for the mass of the atom and contribute to its stability. The nucleus itself is surrounded by a cloud of electrons that orbit around it.
What are the ingrediants of iodine?
Iodine itself is an element, and therefore it has no ingredients other than protons, neutrons, electrons, and atoms.
How many protons neutrons and electrons make up atom of nitrogen-15?
7 protons 7 electrons 8 neutrons
Why does Calcium have different mass numbers but same atomic number?
Atomic numbers are determined by the number of protons an atom has. The mass number is determined by the number of protons and neutrons. While the number of protons can't change (as the element itself would change), neutrons can and do vary. These are called isotopes.
What can a positively charged in an atomic nucleus be?
The atomic nucleus itself has a positive charge. The protons in the nucleus also have a positive charge (the neutrons are neutral). Both protons and neutrons contain "up" quarks, which have a positive charge (the "down" quarks have a negative charge).
Which particles determine the mass of an atom?
The atomic mass unit is defined to be 1/12 of the mass of a carbon-12 atom. Atomic masses can determined by weighing molar amount of an isotope. Absolute masses (in kg) are determined by measuring the amount that charged atoms are deflected by magnets, since if you know the charge you can calculate mass from the amount of deflection.
What is the force needed to hold together a nucleus?
Nuclear force- it is a force that exists between two or more nucleons, it is responsible for the bonding of the neutrons and protons. The reason itself is much more complicated because it involves quarks which are smaller than protons or neutrons.
Is the number of protons equal to the atomic mass minus the atomic number?
No, the number of protons is equal to the atomic number, which is also the same as the number of electrons in a neutral atom. The atomic mass, on the other hand, is the sum of the protons and neutrons in an atom's nucleus.
