How many neutrons are there in zinc-68?
Zinc-68 has 36 neutrons. This can be determined by subtracting the atomic number (number of protons) from the atomic mass (protons + neutrons), which for zinc is 68 - 30 = 38 neutrons.
How many chromosomes are in an elk?
An elk has 68 chromosomes.
How many cc is equal to 68 ml?
68 ml is equal to 68 cc. They are the same unit of volume measurement.
How many yards are in 68 feet?
68 feet are 22.66667 yards.
How many different isotopes of erbium are there?
The formula is Atomic Mass (rounded to the nearest whole number) minus the Atomic Number. This works because Protons and Neutrons have virtually the same mass, and electrons virtually none. As well as the Atomic Number being equal to the amount of Protons. Essentially: Protons + Neutrons - Protons = Neutrons. Basic Prealgebra. So to find the amount of Neutrons in Erbium: Erbium's Atomic Mass rounded (167) - Erbium's Atomic Number (68) = approx. 99 Neutrons
How many protons neutrons and electrons are in erbium?
Erbium has 68 protons, 68 electrons, and varying numbers of neutrons depending on the isotope. The most common isotope, erbium-166, has 98 neutrons.
What charge would tungsten ion with 68 electrons have?
The charge of an ion is determined by the number of electrons it has gained or lost compared to its neutral state. Tungsten has 74 electrons in its neutral state, so if it has 68 electrons, it has lost 6 electrons and would have a charge of +6.
What is the symbol of an ion with 50 protons 68 neutrons and 48 electrons?
The symbol of an ion is determined by the number of protons and electrons. With 50 protons and 48 electrons, this ion has a +2 charge (50 protons - 48 electrons = +2 charge). Therefore, the symbol would be written as Sn2+.
How many neutrons are there in zinc-68?
Zinc-68 has 36 neutrons. This can be determined by subtracting the atomic number (number of protons) from the atomic mass (protons + neutrons), which for zinc is 68 - 30 = 38 neutrons.
How many protons neutrons and electrons for 181Ta 5?
I'm assuming the symbol actually looks like this: 181Ta5+ If that's the case, it means that the mass number is 181, the element is tantalum, and the charge is +5. The atomic number of Ta is 73 (determined from the periodic table, see: http://www.webelements.com), so that tells it has 73 protons. The mass number if the # of neutrons + # of protons, so it has 181 - 73 = 108 neutrons. If it has a +5 charge, it must have 5 electrons less than the number of protons, so 73 - 5 = 68 electrons.
Do you have to pay for 67?
No, but they will charge you double for 68.
What is the chemical symbol for the ion with 73 protons 108 neutrons and 68 electrons?
The atomic number is determined by the number of protons, so the base element is tungsten. The net charge is the number of protons minus the number of electrons, so the overall symbol is W with a 6+ superscript.
What radioactive isotope has 68 protons and 31 neutrons?
Element #68 is Erbium. The number of the isotope, of course, is the sum of the protons + neutrons. Checking the Wikipedia article "Isotopes of erbium", it looks as if this isotope doesn't actually exists.
What has 36 protons 44 neutrons and 36 electrons?
This is the radioactive isotope bromine-78.
What was the Combined point for the 2008 ncaa championship?
