What element has an atomic mass of 84?
Polonium, (element 84), was discovered in 1898 and named after Poland, the homeland of Marie Curie (Ne Sklodowska) who found it with her husband Pierre Curie.
Is curium a metal?
Curium is a hard, brittle, silvery radioactive metal that tarnishes slowly and which can only be produced in nuclear reactors. The isotope 242Cu was produced in 1944 by Glenn T Seaborg, Ralph A James and Albert Ghioso by bombarding 239Pu with alpha particles in the 60-inch Cyclotron at Berkeley University in the US.
Is element 84 a metal?
Although the position of element 84 on the periodic table would lead to categorization as a metalloid, its properties are those of a true metal.
Is Selenium a metal?
Selenium is a metalloid (an element intermediate in properties between the metals and the nonmetals). The gray, metallic form of the element is the most stable under ordinary conditions; this form has the unusual property of greatly increasing in electrical conductivity when exposed to light.
How many electrons does krypton-84 have?

What does the number 84 mean in krypton-84?
The bottom number tells you how many protons you have in the nucleus of this element. In the case of Krypton-84, this means that you have 84 nucleons, where 36 of these are protons, and the remaining 48 are neutrons.
What happens if you eat curium?
After ingestion, most curium is excreted from the body within a few days and never enters the bloodstream; only about 0.05% of the amount ingested is absorbed into the bloodstream.
Is curium used in pacemakers?
A pacemaker is a device that is inserted under the skin that has wire leads implanted into the heart. The pacemaker unit generates the electrical current the heart needs, using the curium battery installed inside of it.
Can selenium be toxic?
Selenium toxicity can occur with acute or chronic ingestion of excess selenium. Symptoms of selenium toxicity include nausea; vomiting; nail discoloration, brittleness, and loss; hair loss; fatigue; irritability; and foul breath odor (often described as “garlic breath”). Selenium is found in the environment in soil.

What does the number 84 mean?
Members of the angel number 84 are hard workers, persistent and they often face many difficulties in the earlier period of their lives. Because they always underestimate their talents and they are incredibly insecure, they become successful and prosperous only later in life(when the gain self-confidence).

What would happen if you ate yellow cake uranium?
Eating large doses of uranium would be very dangerous; if you consumed 25 milligrams of it, you’d immediately start to experience kidney damage, and anywhere past 50 milligrams could cause complete kidney failure and even death.
What does curium smell like?
Curium [Cm 96] was launched in 2016. The nose behind this fragrance is Evelyne Boulanger. Top notes are Red Berries, Ambrette (Musk Mallow), Cinnamon and Pepper; middle notes are Orris Root, iris and Violet; base notes are Benzoin, Musk, Tonka Bean, Patchouli and Vetiver.
Does curium glow in the dark?
Curium is the most radioactive element that can be isolated. It is so intensely radioactive that it boils water, making its chemistry difficult to study. It also glows in the dark (see right). Curium was first intentionally synthesised in 1944 by a team of chemists led by Glenn Seaborg.
