a superscript designating the number of nucleons is placed before the chemical symbol.

Nucleons are either protons or neutrons. Example: Carbon (C) has 6 protons and 6 neutrons.

Carbon-14 has 2 extra neutrons, and is designated 14C

What would happen to the original element if 4 neutrons were added?

If 4 neutrons were added to the nucleus of an original element, it would become an isotope of that element. Isotopes have the same number of protons (and thus the same atomic number) but differ in their mass due to the additional neutrons. This change can affect the stability of the nucleus, potentially making it radioactive if the neutron-to-proton ratio becomes unfavorable. The chemical properties of the element would remain largely unchanged since they are primarily determined by the number of protons.


If one isotope of carbon has 6 protons and 6 neutrons The number of protons and neutrons of a second isotope of carbon would be 6 and 6 7 and 7 6 and 7 or 7and 6?

It would be 6 and 7. Here is why.... The isotope is created when you add a neutron. Protons cannot be added or taken from an atom or it changes the element entirely. Therefore, if you have carbon (6 protons & 6 neutrons) and you add a NEUTRON, you now have the 2nd isotope of carbon. I am positive that you cannot add protons to an atom. The one I am most familiar with is hydrogen. Hydrogen has one proton & ZERO neutrons. If you add one neutron you have deuterium which is the second isotope of hydrogen. If you add two neutrons you have Trittium...... By adding neutrons you have different variations of the SAME ELEMENT! If you added protons to the atom you would have DIFFERENT ELEMENTS! Hope this helps.


Two neutrons added to an atom of the element iridium result in?

If it is possible without any other nuclear reactions to be done, it'll give you an isotope of iridium.


The atomic mass of an atom is equal to the sum of the numbers of what?

The mass number of an atom is the average of all it's isotopes in ratio to how often an isotope occurs naturally (abundance). An isotope is a variant of an element that has a different number of neutrons, therefore causing the atom to have a different mass. The percent abundance of an isotope is converted to a fraction, and multiplied by the mass of the isotope. Then all the factional masses of different isotopes are added together. Atomic mass = (mass isotope 1)x(fractional natural abundance of isotope 1) + (mass isotope 2)x(fractional natural abundance of isotope 2) + (mass isotope 3)x(fractional natural abundance of isotope 3) For example: Hydrogen has 3 naturally occurring isotopes: Protium - Abundance - 99.985% (.99985) Mass - 1.0078 Deuterium - Abundance - .015% (.00015) Mass - 2.014 Tritium - Abundance - 0% (.000) Mass - 3.016 Atomic mass number of Hyrdogen = (.99985)(1.0078) + (.00015)(2.014) + (.000)(3.016) = 1.00795 Go look up the mass number of Hydrogen on the periodic table and it says 1.008


What would happen if a proton was added to a aluminum atom?

If a proton were added to an atom of aluminum, the atom would become a silicon ion with a single positive charge.

What is the symbol for the nucleus of each isotope of uranium?

The symbol for the nucleus of each isotope of uranium is U. Each isotope will have a different number of protons and neutrons, but they will all have the element symbol U as their nucleus.


What is the name of this element that has 8 protons and 9 neutron?

The element with 8 protons is oxygen. To determine the name of the isotope with 9 neutrons, the number of neutrons added to the number of protons gives oxygen-17 which is called oxygen-17.


When the masses of all naturally occurring isotopes of a particular element are averaged the result of the elements?

When the mathematical products of the mass of each naturally occurring isotope of a particular element, each mass being multiplied by the natural abundance fraction* of the particular isotope, are added, the result is called the element's atomic weight or, if the masses are expressed in grams per Avogadro's Number of atoms, the gram atomic mass._____________________________*The abundance fraction equals exactly 0.01 times the percent abundance of the isotope.


What atom has 44 neutrons 35 protons and 35 electrons?

The isotope of bromine called 81-bromine. Since the element you are describing has 35 electrons, it must also have 35 protons. Therefore you end up with bromine which is the 35th element (since the amount of protons are equal to the elements number). Adding 46 to 35 gives you the weight of the specific bromine isotope, since the weight of the element is also the name of the isotope. It is also not radioactive.

What element has 12 protons and 12 neutrons?

Atomic mass is the number of protons added to number of neutrons. Number of protons is element's atomic number, and you can count neutrons by subtracting atomic number from atomic mass. So, it can be any substance which has a atomic number 12 lower than atomic mass. Basically, i would say that it is Magnesium 24 isotope [most common Magnesium isotope], because it has 12 protons and 12 neutrons [12 + 12 = 24] Sodium 23 isotope [also most common] fits perfectly too. However, it can be any other material's isotope. For example Aluminum 25 [13+12=25] Neon 22 [10+12=22]

What happens to an element if an electron is added?

it becomes an ion. an ion of any element has the same number of protons but different number of electrons. an ion can be of two types. cation and anion. cation is positive i.e. one less electron and an anion is negative, i.e. one more electron. so that's the answer to your original question. if an electron is added, the atom of the element becomes negatively charged.


What element results if you add a pair of protons to the nucleus of mercury?

Assuming that two neutrons and two electrons are also added, the atomic number would shift from 80 to 82, resulting in lead. If the neutrons or electrons were not added, it would be the radioactive isotope, lead-206.


Neutral atoms of the same element can differ in their number of what?

Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
