Scandium has a melting point of 1,914 Kelvin, or 2,806 degrees Fahrenheit and a boiling point of 3,109 Kelvin, or 5,136 degrees Fahrenheit with a density of 2.985 grams per centime An atom has 11 protons, 12 neutrons, and 11 electrons. Hello, chemistry lover! 7. The Mass Of The Electrons In This Atom Is About Percent Of The Mass Of The Protons Or Neutrons In This Atom. How To Discover Electrons. Step-1: The atomic number of scandium is the number of protons in scandium's nucleus. What is Scandium's most abundant isotope and how did you know? See the answer. Question: Consider At Atom Of Scandium-42. Multiple Choice 0.05 21. A Zinc (Zn) atom contains 30 protons inside the nucleus, and 30 electrons outside the nucleus. Thus it has 19 electrons. This means it has 3 fewer electrons than the neutral atom or 21 - 3 = 18 electrons. Making Sc 3+ Imagine you are building a scandium atom from boxes of protons, neutrons and electrons. What is an isotope? Number of neutrons depends on the isotope. Valence electrons can be determined by looking at the periodic table; because titanium is four columns from the left, it has four valence electrons. SSc is the only naturally occurring isotope of scandium. Calculate the atoms of Sc contained in the sample. 0 0. Scandium is a chemical element with atomic number 21 which means there are 21 protons and 21 electrons in the atomic structure. True d) Some atoms don’t have any protons. So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. Scandium is the 21st element of the periodic table having mass number 45.
