What is the atomic mass for strontium?
87.62 Wrong, that is the Atomic Mass, not the Mass Number. The Mass Number is the whole number of protons plus neutrons for the specific isotope. For example, Sr-88 is a stable isotope, with 88-the atomic Number 38 being the number of neutrons. Complicating the matter, Sr 86 and Sr 87 are also stable but would have mass numbers of 48 and 49.
What is an isotope of strontium that has 52 neutrons?
Strontium-88 is an isotope of strontium that has 52 neutrons. It has an atomic number of 38, therefore the total number of neutrons (52) is obtained by subtracting the atomic number from the mass number.
What element's isotope of mass 90 is formed when sr-90 emits beta particles?
Yttrium-90 is formed when strontium-90 emits beta particles. This is because the decay of strontium-90 involves the transformation of one of its neutrons into a proton, resulting in the element yttrium with a mass number of 90.
How many neutrons are in Sr 2 plus?
Strontium (Sr) has an atomic number of 38, meaning it has 38 protons. The most common isotope of strontium is Sr-88, which has 50 neutrons (88 total nucleons minus 38 protons). The Sr²⁺ ion indicates that it has lost two electrons, but the number of neutrons remains unchanged, so Sr²⁺ still has 50 neutrons.
What is the mass number for the element uranium?
The atomic weight of uranium is 238,02891(3) atomic mass units. The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope: 234U: mass number 234 235U: mass number 235 238U: mass number 238

How to find the number of neutrons in an isotope?
Atomic mass is the sum of protons plus neutrons, while atomic number counts only the protons. So subtract atomic number from mass number to get neutron number. For example, Strontium (Sr) has atomic number 38. So Sr-90 holds 90 - 38 = 52 neutrons in its nucleus.
What is the atomic mass for calcium?
the atomic mass for calcium is 40.078 sr
What is the atomic number of Sr?
Strontium is a metal element. atomic number of it is 38.
How many atoms are in 16.3 g of Sr?
To determine the number of atoms in 16.3 g of strontium (Sr), you first need to calculate the number of moles using the molar mass of Sr (87.62 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. The final calculation results in approximately 1.11 x 10^23 atoms of strontium in 16.3 g.
What is an isotope of strontium that has 52 neutrons?
Strontium-88 is an isotope of strontium that has 52 neutrons. It has an atomic number of 38, therefore the total number of neutrons (52) is obtained by subtracting the atomic number from the mass number.
What is the ship that you use in the Mass Effect series?
The SSV Normandy in Mass Effect The Normandy SR-2 in Mass Effect 2 & 3
What is the period number for strontium?
Strontium (Sr) is number 38
Name of sr(io)4?
Strontium Periodate and it has a molar mass of 469.4241
What is the phone number of the Wheeler Taft Abbett Sr in Tucson?
The phone number of the Wheeler Taft Abbett Sr is: 520-594-5200.
What element's isotope of mass 90 is formed when sr-90 emits beta particles?
Yttrium-90 is formed when strontium-90 emits beta particles. This is because the decay of strontium-90 involves the transformation of one of its neutrons into a proton, resulting in the element yttrium with a mass number of 90.
What was Dale Earnhardt Sr's car number in 1980?
Dale Sr. drove the #2 car in 1980.
