What number is added to an element to specify its isotope?
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 can be added or taken away from an atom to change the atomic mass?
The atomic mass of an atom can be changed by adding or removing subatomic particles. By adding or removing protons, neutrons, or electrons, the atomic mass will be altered. Changing the number of protons will change the element, while changing the number of neutrons will create isotopes of the same element.
What is the 150th element in the periodic table of elements?
After taking out my periodic table of elements, the closest i could find would be Californium, with 153 neutrons, Berkelium, with 152 neutrons, and finally Curium with 151 neutrons. This can be found by taking the atomic number of an element (which is the number of protons it has) and subtracting it from the elements atomic mass (which is the number of protons and neutrons added together). No element has a perfect 150 neutron number, but in its most stable isotope form Curium appears to be the closest.
What can we find on the periodic table?
The Periodic table is a table with more than a hundred Elements on it. As of 2010, there are 118. Along with the names of the Elements there is the chemical symbol of the Element, the atomic number, and usually the atomic mass of the Element. The atomic number represents the number of Protons in one atom, and the atomic mass is the mass of the Protons and neutrons added together. The Electrons are not added onto the mass of the Protons and Neutrons because the Electrons are negligible.
What effect produced by changing the number of neutrons in the nucleus of an atom?
What differentiates one element from another (like Hydrogen from Helium) is the number of protons in the nucleus. When protons are added (as happens in nuclear fusion) or subtracted (nuclear fission), the element transmutes into another element. When the number of Protons are changed, both the Electrons and Neutron (numbers) will change too. Protons are paired with electrons. Protons + Electrons = Neutrons, thus reinforcing that both the Electrons and Neutrons will change when the number of Protons has.
Which element would you have if you added 4 protons and 4 neutrons to titanium?
Adding 4 protons and 4 neutrons to titanium would result in the element Chromium. Chromium has an atomic number of 24, which is 4 more than titanium's atomic number of 22, and both elements have a similar arrangement of protons and neutrons.
What do we call it when neutrons are added to an element?
This is a (n,γ) nuclear reaction (neutron-gamma).
What is totalled to get the mass number of an element?
the number of protons and neutrons added together
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.
Isotopes exist because atoms of the same element can have a different numbers of what?
Isotopes are different atoms of the same element with the same number of protons (proton number) but different in number of neutrons. Given that nucleon number is equal to the sum of proton and neutrons in the nucleus of an atom, isotopes have different nucleon number due to difference in number of neutrons.
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.
Atoms of the same element can differ in?
An atom is made of 3 key componants, proton, neutron and electron. Different amounts of protons in the atom make it a different element, e.g carbon 12 is an element with 12 protons AND neutrons, so 6 protons and 6 neutrons. So if a proton is added to an atom, it creates a different type of atom....but.....if another Neutron is added, for example, making carbon 12-->carbon 14 by adding 2 neutrons, this makes it an isotope of carbon, as carbon would normally be found as carbon 12. So an isotope is an atom with an unnatural amount of neutrons within it.
What is the number of protons and neutrons called?
The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
What number is added to an element to specify its isotope?
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
Why doesnt the number of protons change for a single element while the neutrons and electrons can?
The number of protons in an atom determines its identity as a specific element. Changing the number of protons would change the element. Neutrons and electrons can be added or removed without changing the identity of the element since they do not affect the element's chemical properties.
What can be added or taken away from an atom to change the atomic mass?
The atomic mass of an atom can be changed by adding or removing subatomic particles. By adding or removing protons, neutrons, or electrons, the atomic mass will be altered. Changing the number of protons will change the element, while changing the number of neutrons will create isotopes of the same element.
