What period on the table is scandium?
Scandium is found in period 4 on the periodic table. It has an atomic number of 21 and is classified as a transition metal.
What is the 21 element?
The element with the atomic number 21 is Scandium. Scandium is the first transition metal and is in Group 3, Period 4 of the Periodic Table. It has 21 electrons in 4 shells with 2 electrons in the outer shell.
Which element in Period 5 of the Periodic Table is a transition element?
Vanadium Niobium Tantalum
An emement x has mass number 40 and contains 21 neutrons in its atomto which group and priod of the priodic table does it belong?
The element with mass number 40 and 21 neutrons is Calcium (Ca), which belongs to Group 2 and Period 4 of the periodic table. It has 20 protons (40 - 21 = 20) in its nucleus, making it the 20th element in the periodic table.
Is scandium soft or hard?
Scandium is a transition metal that is soft and silvery-white in appearance. It is a malleable and ductile element. Scandium has 21 protons and 24 neutrons.
How many protons and neutrons are there in the element scandium?
21 protons and 24 neutrons in the only stable for. But there can be as few as 15 and as many as 39 neutrons.
Is iron is a transition element?
Yes, elements from atom number 21 (Sc) to 30 (Zn) are the so called '3d-block'transition-elements, group 3 to 12 in period IV of the periodic table.
What has 22 protons and 21 neutrons?
Titanium is the element having 22 protons and 21 neutrons. Its symbol is Ti.
What element has 21 neutrons?
An element with 21 neutrons would have an atomic number of 11, as the number of protons in an atom determine its atomic number. Therefore, the element would be sodium (Na), which has an atomic number of 11 and typically has 12 neutrons.
Is Zn group should be considered as transition elements?
No, zinc (Zn) is not typically considered a transition element. Transition elements are elements in groups 3 to 12 on the periodic table. Zn is located in group 12, which is not part of the transition element block.
How many neutrons does the element Sc have?
The element Scandium (Sc) has 21 protons in its nucleus, which can be determined using its atomic number. To find the number of neutrons, we can subtract the atomic number from the atomic mass: Scandium has an atomic mass of approximately 45. This gives us 45 - 21 = 24 neutrons in a Scandium atom.
What is the name of the element in group3 period 4?
The element in group 3 and period 4 of the periodic table is scandium, with the atomic number 21. It is a silvery-white transition metal known for its lightweight properties and is commonly used in aerospace industry and sports equipment.
