What is the atomic number of Sr?
Strontium is a metal element. atomic number of it is 38.
How many protons does strontium have?
You can tell how many protons an element has from its atomic number. So the atomic number of Strontium is 38..so it has 38 protons.
All atoms of an element with atomic number 38 and mass number 88 contain?
All atoms of the specified data contain 38 protons, 38 electrons (assuming they are not ions), and 50 neutrons. They are atoms of the element Strontium.
What is the atomic number for strontium chloride?
The atomic number for strontium chloride is determined by the element strontium, which has an atomic number of 38. Since chloride is an anion with a charge of -1, it does not affect the overall atomic number of the compound.
What element has 18 protons 20 nuetrons and 18 electrons What is its atomic number?
The atomic number of am element is determined by its number of either electrons or protons, hence here, it is 18. Therefore the element must be argon which the isotope has mass number 38, as there are 18 protons and 20 neutrons.
How many electrons are in argon- 38?
Argon-38 is a specific isotope of argon, and it has 18 electrons since the number of electrons in an element is determined by its atomic number.
What is the mass number of an atom with 19 protons and 20 neutrons?
The element is potassium. Atomic mass is 38.
What element has a atomic mass of 39.9?
The atomic number is the count of how many protons an atom has in its nucleus (and therefor also the count of how many electrons the neutral atom possesses). The atomic number us unique for each element and positions the element in the periodic table. The element with atomic number 39 is Yttrium (Y).
What is the atomic number of strontium?
The atomic number of strontium (Sr) is 38.The atomic weight of Sr is 87.62 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
What element has 38 protons and 36 electrons?
The element with 38 electrons is Strontium (Sr). Strontium is an Alkaline Earth Metal in Period 5 of the Periodic Table. Strontium has 38 electrons, 5 electron shells and 2 electrons in the outer shell.
There are no known stable isotopes of the element with an atomic number of a 56 B 38 C100 D 20?
Element 20 is Tin. Element 38 is Strontium. Element 56 is is Barium. Element 100 Fermium. Fermium is artificially created, and has no stable isotopes. In general, there are no stable isotopes heavier than Bismuth (element 83).
What element has an atomic number between 37 and 41?
37 - rubidium 38 - strontium 39 - yttrium 40 - zirconium 41 - niobium
