There are no known stable isotopes of the element with an atomic number of a 56 B 38 C100 D 20?
The element with an atomic number of 100 is Fermium (Fm), which does not have any stable isotopes. Fermium is a synthetic element that is produced in nuclear reactors and has only radioactive isotopes. Stable isotopes have a balance of protons and neutrons that result in a nucleus that does not undergo radioactive decay.
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).
This element has an atomic number that is double the atomic number of silicon?
this elemnt has an atomic number that is double the atomic number of silicon?
This element has the atomic number that is double the atomic number of silicon?
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
Element has an atomic number that is double the atomic number of silicon?
The element with an atomic number that is double the atomic number of silicon is germanium, with atomic number 32. Silicon has an atomic number of 14.
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!
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 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 does the abbreviation SR refer to in chemistry?
Sr is the abbreviation for Strontium - a chemical element (symbolSr and atomic number38). An alkaline earth metal, strontium is a soft silver-white or yellowish metallic element that is highly reactive chemically.
What atom has the following abbreviated electron configuration of Kr 5s2?
Sr, Strontium (atomic number 38)
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 atomic mass for calcium?
the atomic mass for calcium is 40.078 sr
What atomic radius is larger Rb or Sr?
The atomic radius of Sr (Strontium) is larger than that of Rb (Rubidium). This is because atomic radius generally increases down a group in the periodic table, and Sr is located below Rb in the same group.
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.
