An element has 22 protons 20 electrons and 26 neutrons What isotope is it?

The element with 22 protons is titanium (Ti). The sum of protons and neutrons determines the isotope, so with 26 neutrons, the isotope is titanium-48 (22 protons + 26 neutrons = Ti-48).


How many protons electrons and neutrons in the element kalsium?

1) it's spelt Calcium and 2) 20 protons, 20 electrons, 20 neutrons


What isotope has 20 protons and 22 neutrons?

The number on the periodic table is the number of protons it contains. The isotope number is the sum of the protons and neutrons.Therefore, the isotope with 20 protons and 22 neutrons is Calcium-42.


What element has 41 neutrons and 20 protons?

This isotope don't exist.Added:That's right, the element with atom number 41 has 41 protons and should be :Naturally occurring niobium which is composed of one stable isotope, 41Nb(93)This means that the mass number (= total of protons AND neutrons) is 93!, so this isotope of Nb has 93-41 = 52 neutrons!As of 2003, at least 32 radioisotopes have also been synthesized, ranging in atomic mass from 81 to 113, so they have 40 to 82 neutrons. This makes the amount of 20 neutrons erronous.However: if the question were 'inverted' to:"What element has 21 (not 41) protons and 20 neutrons" instead, there is a possible more realistic question.The answer to this is: scandium, 21Sc(41) This unstable isotope of Sc, with mass number 41, has 21 protons and 20 neutrons.


How many protons and neutrons are there in the sulfur-36 isotope?

16 protons 20 neutrons


How many protons electrons and neutrons in the element potassium?

The atomic number of potassium is 19. So there are 19 protons and 19 electrons. The number of neutrons depends on the isotope. The most stable isotope of potassium (K-39) has 20 neutrons (39 - 19 = 20).


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.)


How many protons electrons and neutrons in calcium-44?

Ca-46 is an isotope of the calcium found on the periodic table. The atomic number is equivalent to how many protons the atom has and tells the identity of the element, if the number of protons is changed/ atomic mass number, the element would transmutate into another element. Thus, Ca always has 20 protons. Because it is not Ca++ or Ca- it is not changing the charge so no electrons are moving either. This means the number 46 is refering to a change in neutron in the nucleus of the atom, hence it is called an isotope. 46 is the number of protons plus neutrons so the isotope of Calcium has 20 protons, 20 electrons and 26 neutrons, or 46-20=26. Hope this clarifies things.


Calcium has an atomic mass of an atomic number of 20 so the number of neutrons must be?

The number of neutrons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass. For calcium with an atomic number of 20, if the atomic mass is 40, then the number of neutrons would be 40 - 20 = 20 neutrons.


What can you say about an atom of an element which has 17 protons 18 electrons and 20 neutrons?

This is the ion Cl- of the isotope chlorine-37.


How many protons neutrons and electrons are in cl?

Cl-35 isotope has 18 neutrons Cl-37 isotope has 20 neutrons


What element has 18 protons 20 nuetrons and 18 electrons What is its atomic number?

The element with 18 protons is argon (Ar), with atomic number 18. Its mass number is calculated by adding the protons and neutrons, so 18 protons + 20 neutrons = mass number 38 for this particular isotope of argon.
