∙ 16y agoto find the mass number add together the protons and neutrons, which each have a relative mass of one. electrons can be ignored as their relative mass is negligible (1/1836). So, 21 + 24 = 45 The element in question would be scandium

How many electrons neutrons and protons are in scandium?
Because its atomic number is 21, it has 21 protons, 21 neutrons, and 21 electrons.
If an atom has 11 protons 12 neutrons and 11 electrons what is the identify of the element and it's mass number?
It is a radioactive scandium isotope - 43Sc with 21 electrons and protons, and 22 neutrons.
How many protons neutrons and electrons are in k40?
K always has 19 protons, because that is what defines it as an element.40, the atomic mass is the sum of protons and neutrons. So if you subtract the number of protons from the atomic mass, you get the number of neutrons.40-19=21 neutrons
How many protons neutrons and electrons are in Sc atomic number 44?
Sc is actually atomic number 21, there are 21 protons, 21 electrons, and usually 24 neutrons
What element has 21 neutrons?
Lead has 125 neutrons It's element symblo is Pb
How many electrons neutrons and protons are in scandium?
Because its atomic number is 21, it has 21 protons, 21 neutrons, and 21 electrons.
How many protons neutrons and electrons in Sc with mass number 44?
21 protons, 21 electrons and 23 neutrons
How many neutrons does the element Sc have?
The atomic number of scandium is 21. So it has 21 protons and 21 electrons. Number of neutrons depends on the isotope. Number of neutrons = Mass number - Atomic number Sc-45 isotope has 24 neutrons
How many protons neutrons and electrons are in the element cobalt?
There are 21 electrons and protons in the element Cobalt, and there are 58.933195 neutrons or 36.933195. If your working on a project and your in elementary or middle school you are very smart.Well Done. -Emily (5th Grader)
What are the numbers of protons and neutrons of 45 21Sc?
21 protons, 21 electrons and 24 neutrons in 21Sc45 isotope.
If an atom has 11 protons 12 neutrons and 11 electrons what is the identify of the element and it's mass number?
It is a radioactive scandium isotope - 43Sc with 21 electrons and protons, and 22 neutrons.
How many protons neutrons and electrons are in k40?
K always has 19 protons, because that is what defines it as an element.40, the atomic mass is the sum of protons and neutrons. So if you subtract the number of protons from the atomic mass, you get the number of neutrons.40-19=21 neutrons
What has 22 protons and 21 neutrons?
Titanium is the element having 22 protons and 21 neutrons. Its symbol is Ti.
How many protons neutrons and electrons are in Sc atomic number 44?
Sc is actually atomic number 21, there are 21 protons, 21 electrons, and usually 24 neutrons
How much protons neutrons and electrons does manganese have?
25 protons 25 electrons normally 30 neutrons but it can vary between 21 and 40.
How many protons neutrons and electrons an atom of titanium have?
Protons: 21 Neutrons: 29 Electrons: Normally 21
What element has 24 protons and 21 electrons?
An element's number of protons is the same as its atomic number. Thus, an atom with 21 protons has the atomic number 21. By looking up this element on the periodic table, one finds that it is scandium.
