What else can I help you with?
Why must you know both how many protons and how many neutrons an element has in order to fully identify it?
The number of protons determine what element it is, the number of neutrons determine what isotope it is.
How do you determine the number of neutrons in an element?
To determine the number of neutrons in an element, subtract the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). Neutrons are neutral particles found in the nucleus of an atom.
If an element has a mass number of 208 and an atomic number of 83 how many neutrons does the element have?
To determine the number of neutrons, subtract the atomic number from the mass number. In this case, 208 - 83 = 125 neutrons.
What does the number of neutrons determine?
The number of neutrons in an atom determines the isotope of the element. Isotopes of an element have the same number of protons but differing numbers of neutrons. This affects the stability and nuclear properties of the atom.
How do you determine the mass of an element?
The mass of an element is the sum of the protons and neutrons in an atom. It is usually listed right on the periodic table.
How do you determine the isotope?
Isotopes are determined by the number of neutrons in an atom's nucleus. Each isotope of an element has the same number of protons in its nucleus but a different number of neutrons. Isotopes of an element have the same chemical properties but different atomic masses.
What part of the nucleus determine the atomic mass for an element?
All parts of the nucleus, protons and neutrons if any, contribute to the atomic mass. The total number of protons and neutrons in an atom is its isotope mass number.
What element has 44.96 neutrons?
To determine the element with 44.96 neutrons, we need to find an element with an atomic number close to this value. Based on the periodic table, an element with an atomic number of 28 (nickel) has 31 neutrons and an element with an atomic number of 30 (zinc) has 35 neutrons. Therefore, an element with 44.96 neutrons likely does not exist in the periodic table.
Which particles are in the nuleus of an atom?
Inside of an atom there are protons and neutrons. The protons determine the element whereas the neutron can determine if it is an isotope of that element. Of course there are many smaller particles inside of protons and neutrons like quarks and gluons and ... strings.
How can you use the periodic table to determine the average number of neutrons and elements has even though the number of neutrons is not listed?
To determine the average number of neutrons in an element using the periodic table, first locate the element's atomic mass (usually a decimal number) and its atomic number (a whole number). The atomic number represents the number of protons, while the atomic mass is approximately the sum of protons and neutrons. By subtracting the atomic number from the atomic mass and rounding to the nearest whole number, you can estimate the average number of neutrons for that element.
What three particles determine which element you have?
An atom of an element is comprised of protons, electrons, and usually neutrons. The specific element is determined by the number of protons, and so there is only one particle that determines the element.
How many neutrons are in the element gold?
There are 118 neutrons in the element gold.
