as
it is actually "As"
the "A" has to be capitalized to be correct, or it could stand for something totally different.
In addition to the above, it might be helpful to see how the answer is derived:-
First deduct the number of neutrons from the mass number -
73 minus 40 equals 33
This gives the Atomic Number 33. Reading down the Periodic Table to find element number 33, we find that it is Arsenic, chemical symbol As.

∙ 13y agoIt has 41 (mass) - 21 (neutrons) = 20 protons, so its atomnumber is 20, which happens to be element Calcium. However Ca-41 is not naturally occurring, though it is quite stable (half-life time > 100,000 year).
Wiki User
∙ 12y agoThe (only) element with atom number 33 is Arsenic(atom numbers are unique and equal to proton number).
With 41 neutrons it has to be isotope As-74 (the mass number is 74, because 33 protons + 41 neutrons = 74 mass).

What element has a mass number of 44?
The closest to 44 is Scandium, which has 21 protons and 24 neutrons, giving it a mass of 44.95591 amu.
How many neutrons are in a neutral atom of calcium with a mass number of 41?
41 amu 41 amu
An isotope of iron has 26 protons and 32 neutrons what is the mass number?
An unknown element contains 24 protons, 21 electrons,and has mass number 54
An atom with a mass number of 45 has three more neutrons than protons What is the atomic number of this atom?
The atomic number is 21: The mass number is the sum of protons and neutrons, while the atomic number is the number of protons, designated n. From the statement of the problem, n+n+3 = 45, or 2n = 42, or n=21.
An atom of Potassium has a mass number of 40 and an atomic number of 19.how many protons does it have?
The atomic number is the number of protons: 19.number of neutrons = mass number - atomic number = 21.The number of electrons is normally the same as the number of protons: 19
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
what element has 21 protons 21 electrons and 24 neutrons?
chromium
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
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.
What is the difference between mass no and atomic no of an atom gives the number of?
Atomic number is the number of protons in the nucleus of an atom. The mass number however is the sum of the protons and neutrons in the nucleus of an atom. Each element has one specific atomic number (= no. of protons), but can have more different number of neutrons, hence it might have different mass numbers, those atoms are called 'isotopes' of an element. Examples are given below Calcium: Ca(40) has 20 protons and 20 neutrons (mass no. 40) Ca(41) has 20 protons and 21 neutrons (mass no. 41) Kalium: K(40) has 19 protons and 21 neutrons (mass no. 40) K(41) has 19 protons and 22 neutrons (mass no. 41)
What is the chemical symbol of the element who is the mass number is 80?
A-N=Z Mass number - Number of neutrons= Atomic number mass number = 80, number of neutrons = 41; 80-41=39 Atomic number for the element with mass number 80 and 41 neutrons; is 39.
What element has a mass number of 44?
The closest to 44 is Scandium, which has 21 protons and 24 neutrons, giving it a mass of 44.95591 amu.
What element has 19 protons 21 neutrons and 18 electrons?
ONLY the K+ ion (not element) has 19 protons and 18 electrons.The isotopic ion with 21 neutrons must be K+-40 , the most rare potassium-ion (0.01%) out of three possibles, the other isotopes are: K+-39 (93%) and 7% is K+-41Explanation:39, 40 and 41 are the mass numbers of the 3 naturally occurring potassium isotopes.Keep in mind that:1. an element is always neutrally charged, so the number of protons (positives, + ) equals the number of electrons (negatives, - )2. the number of neutrons depends on the 'mass number' of the one particular isotope of that element and that the number of protons + neutrons is the mass number
How many protons neutrons and electrons in Sc with mass number 44?
21 protons, 21 electrons and 23 neutrons
What is the mass of an element that contains 10 protons and 11 neutrons?
This is the isotope neon-21 with the atomic mass 20,99384668(4).
If scandium has 24 neutrons how many protons does it have?
To figure this out look at the mass number of scandium. It has a mass number of 45(im rounding it up to keep it simple). The mass number is the number of protons and neutrons that form the nucleus added together. So if we know 24 of these 45 particles have to be neutrons then there must be(45-24)= 21 protons. To check this awnser we look at the atomic number(the one above the symbol for the element) and we can see that it is 21 for scandium meaning our awnser is correct.
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.
