Is mendelevium a metal?
The following are the key properties of mendelevium: It is a radioactive rare earth metal. It has a moderately stable divalent state in addition to a trivalent state.
What is a semiconductor metal nonmetal metalloid?
Metalloids have properties intermediate between the metals and nonmetals. Metalloids are all solid at room temperature. They can form alloys with other metals. Some metalloids, such as silicon and germanium, can act as electrical conductors under the right conditions, thus they are called semiconductors.
How is mendelevium formed?
Mendelevium has no known biological role. Mendelevium does not occur naturally. It is made by bombarding einsteinium with alpha particles (helium ions).
What compound is mendelevium in?

Where is mendelevium found on the periodic table?
In the periodic table, mendelevium is located to the right of the actinide fermium, to the left of the actinide nobelium, and below the lanthanide thulium.
What is mendelevium in the periodic table?
mendelevium (Md), synthetic chemical element of the actinoid series of the periodic table, atomic number 101. It was the first element to be synthesized and discovered a few atoms at a time.
What is a semiconductor metalloid?
Metalloids are semiconductors because they are neither good nor poor conductors. The valence electrons of metals are not bound to any particular atom. Their electronic structures are intermediate between those of metals and nonmetals. Thus, they conduct electricity better than nonmetals but not as well as metals.
What are the differences between metals nonmetals and metalloids?
A metal is an element which is typically hard, shiny, fusible, malleable, and ductile, with good electrical and thermal conductivity. A metalloid is an element having intermediate properties of both metals and nonmetals. This is the main difference between metals nonmetals and metalloids.
What is the electron configuration of mendelevium?

Is mendelevium a lanthanide?
In the periodic table, mendelevium is located to the right of the actinide fermium, to the left of the actinide nobelium, and below the lanthanide thulium. The lanthanides and actinides, in the metallic state, can exist as either divalent (such as europium and ytterbium) or trivalent (most other lanthanides) metals.
Is mendelevium an isotope?
Mendelevium (101Md) is a synthetic element, and thus a standard atomic weight cannot be given. Like all artificial elements, it has no stable isotopes.
What does metalloid mean on the periodic table?
Metalloids • The periodic table contains a stair-step line, these elements along that line are called metalloids. • The “-oid” ending means – like or similar to • Elements in this group have properties of both metals and non-metals. 12. Physical Properties of Metalloids • Solids that can be shiny or dull.
What are the physical properties of non metals?
Physical Properties of Non-Metals • poor conductors of heat and electricity. • Non-metals are not ductile or malleable. • Solid non-metals are brittle and break easily. • Dull, no shiny luster, don’t reflect light.
Where are the nonmetals on the periodic table?
Nonmetals Properties of Nonmetals Nonmetals occur to the right of the dark zig-zag on the periodic table. Although Hydrogen is in family 1, it is also a nonmetal. Many nonmetals are gases at room temperature. Properties of Nonmetals Nonmetals do not have luster; they are dull.
What makes a metal better than a nonmetal?
• Metals are shiny, malleable and good conductors whereas nonmetals are dull, brittle and don’t conduct electricity (insulators). 3. You are given a battery, a bulb, and wires. How could you use these materials to determine if an unknown solid was a metal or a non-metal?
