Which two solid metal elements might scientists use to create an element with an atomic number of 129?
Strontium(Sr) and Radium(Ra)
What is the electron configuration for element kr?
The lowest atomic number ion is Se^2-. The highest atomic number ion is Sr^2+. The ones in the middle are NOT Br^- or Rb^+. However, I do not know what the correct answer for those two is.
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?
Which element has an atomic number between 27 and 31?
Atomic number 27 : Cobalt Atomic number 28 : Nickel Atomic number 29 : Copper Atomic number 30 : Zinc Atomic number 31 : Gallium
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 is the element represented by the symbol Sr?
It represents the element with the atomic number of 38 Strontium
What atom has the following abbreviated electron configuration of Kr 5s2?
