What else can I help you with?
Which of the following is unique for any given element A the number of protons B the number of neutrons C the charge on the electrons D the mass of the neutron?
its atomic numberthe number of neutrons
What term best indicates the total number of neutrons and protons in a particular isotope of an element?
The atomic mass number is the sum of the protons and neutrons of an element. The protons are given by the atomic number, so the neutrons can be found by subtracting the mass number by the atomic number. Both the mass and atomic numbers can be found on the periodic table.
What subatomic particles could be changed without changing which element the atom?
You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.
What is the element that has 20 neutrons?
Several can. Perhaps you meant to ask which has 20 protons, in which case the answer is calcium. (Calcium is also one of the elements that can have 20 neutrons, but it's not the only one.)
What has 22 protons and 21 neutrons?
Titanium is the element having 22 protons and 21 neutrons. Its symbol is Ti.
What element has 8 neutrons 8 protons?
The element that has 8 protons and 8 neutrons is oxygen.
An element's atomic mass number is?
It is about neutrons and protons. The total of neutrons and protons.
How many protons and neutrons are in the element?
Neon has 10 protons and 9 neutrons.
What element has 11 protons and 13 neutrons?
Sodium, Na, is the element that has eleven protons.
What element has six protons and six neutrons?
carbon has six protons and six neutrons
What is the name number tells you the amount of protons and neutrons in an element?
Number of protons + Number of neutrons = Mass number(number of nucleons)
How is an element with 56 protons and 82 neutrons related to an element with 56 protons and 78 neutrons?
They are both Isotopes of Barium. The 56 protons tell us that the element is Barium and when you add the neutrons with the protons you get barium138 and barium134. They are both stable isotobes of barium but of all the barium in the world about 72% is barium138 and 2% is barium134.
What element have 25 protons and 30 neutrons?
Manganese (the natural isotope 55Mn) has 25 protons and 30 neutrons.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
What element has 9 electrons 9 protons and 10 neutrons?
The element is Neon and the isotope is 10Ne19
What element has the same number of neutrons and protons?
Atoms having the same number of protons and neutrons make up the same element.
What element has 6 protons and 8 neutrons?
The element with 6 protons and 8 neutrons is carbon-14, which is a radioactive isotope of carbon.
