What element has a mass number of 75 and 33 protons?
arsenic
To get its mass number, you need to round its atomic mass to the nearest whole number. Therefore, the stable arsenic isotope is arsenic-75, 75As , which has 33 protons and 42 neutrons in its nucleus.
How many protons does 75 33 have?
Arsenic-75 33 protons 42 neutrons 33 electrons B.
How many neutrons does 75 33 as have?
42 neutrons
Diagram of the nuclear composition and electron configuration of an atom of arsenic-75 (atomic number: 33), the most common isotope of this element. The nucleus consists of 33 protons (red) and 42 neutrons (blue). 33 electrons (green) bind to the nucleus, successively occupying available electron shells (rings).
What element has a proton number of 33?
Arsenic
Arsenic has an atomic number of 33. That means it has 33 protons in its nucleus and 33 electrons buzzing around the nucleus, when it is uncharged.
What has a mass number of 33?

How many protons neutrons and electrons does s 33 have?
Sulfur has 23 known isotopes, four of which are stable: 32S (94.99%±0.26%), 33S (0.75%±0.02%), 34S (4.25%±0.24%), and 36S (0.01%±0.01%). Sulfur-32 is composed of 16 protons, 16 neutrons, and 16 electrons. Sulfur-33 is composed of 16 protons, 17 neutrons, and 16 electrons.
How many protons does 33S 2 have?
16protons
33the mass number=16protons+17neutrons .
How many neutrons does as 74 have?
The atomic number of tungsten is 74, so a tungsten atom has 74 protons. Mass number = number of protons + number of neutrons= 184. So number of neutrons = relative atomic mass – number of protons = 184 – 74 = 110.
How many protons does arsenic 76?

How many protons and neutrons are there in barium 137?
Explanation: When the element is barium, that means the aomic number is 56 which you see by looking for barium on a periodic table (or nowdays by entering “barium” into an online search engine). Thus the “barium” in “barium 137” means 56 protons. And the 137 for the mass number designates 137 total protons protons plus neutrons.
How to find the number of protons in an element?
The symbol for an isotope of an element such as #”O”# is often written as #””_8^16″O”^n#. The #”O”# is, of course, the symbol for an oxygen atom. The subscript represents the atomic number #Z#, the number of protons in the nucleus.
Which is the atomic number, atomic mass, neutrons?
We see that for mercury the atomic number is 80. The atomic number is the number of protons in an atom’s nucleus, so we can tell right away that an atom of mercury contains 80 protons. The mass number (201) is the total number of protons and neutrons.
What is the atomic number of an atom?
Atomic number — number of just protons in the nucleus. The atomic number determines what an element is chemically, for the number of protons determines the number of electrons needed to balance the charges in an atom, which in turn determines the electron configuration the atom will adopt. Mass number is the number of protons plus neutrons.
