What is the boiling point of the element lawrencium?
The boiling point of lawrencium is not precisely known since it is a synthetic element that only exists in tiny amounts for a very short period of time. However, it is estimated to have a boiling point around 1,627 degrees Celsius.
Which element is likely to combine with a nonmetal K Ar F or Br?
K, potassium being a metal is highly reactive towards non metals.
What element has one valence electron but is not a metal?
There is no non-metal with one valence electron. Every element with 1 valence electron belongs to the alkali metals family
The element argon is the last element in its period What does this tell you about?
This tells us that argon has a full outer electron shell, making it stable and unreactive. Elements at the end of a period often have filled electron shells, giving them properties different from other elements in the same period.
Why is hydrogen classified as a halogen?
Hydrogen is not classified as a halogen. Halogens are a group of elements on the periodic table that includes fluorine, chlorine, bromine, iodine, and astatine. Hydrogen is a nonmetal element that belongs to a different group on the periodic table.
Is oxygen a metal metalloid or a nonmetal?
Oxygen is nonmetal because since oxygen isn't visable it's not solid so oxygen is nonmetal.
What is the boiling point of the element lawrencium?
The boiling point of lawrencium is not precisely known since it is a synthetic element that only exists in tiny amounts for a very short period of time. However, it is estimated to have a boiling point around 1,627 degrees Celsius.
What are the kinds of nonmetal atoms?
Any element that is not a metal is, by definition, a nonmetal. These come in basically two types, the chemically active nonmetal and the inert nonmetal. Sulfur, oxygen, nitrogen, carbon, silicon, phosphorus, and the halogens, fluorine, chlorine, bromine, iodine, and astatine, are the most important of the chemically active nonmetals; hydrogen is an ambiguous element since it can be either a metal or a nonmetal, although it is usually a nonmetal (note that at low temperature and high pressure, hydrogen actually will become a metallic solid, with all the usual features of a metal, even though under more usual temperatures and pressures it is a transparent gas bearing no resemblance to a metal). The inert nonmetals are the noble gases, helium, neon, krypton, xenon, and radon.
How do you use for and since?
You use for when talking about a period of time.I have known him for 5 years.You use since when talking a bout a point in time.I have known him since 1999.
Which element is likely to combine with a nonmetal K Ar F or Br?
K, potassium being a metal is highly reactive towards non metals.
What element has one valence electron but is not a metal?
There is no non-metal with one valence electron. Every element with 1 valence electron belongs to the alkali metals family
What kind of charge will nonmetal possess when it gains electron?
Since electrons are negatively charged, a nonmetal which gains an electron will also become negatively charged.
Which element was once called argentum?
The element that was once called Argentum is Silver. It came from the Latin Argentum, meaning silver. It has been known since prehistoric time.
Who found the element lead?
It was known since prehistoric times- and like Gold, is mentioned in the Bible as a synonym for heaviness.
The element argon is the last element in its period What does this tell you about?
This tells us that argon has a full outer electron shell, making it stable and unreactive. Elements at the end of a period often have filled electron shells, giving them properties different from other elements in the same period.
Who discovered element number 6?
Element number 6, carbon, was known since ancient times and does not have a single discoverer. However, Antoine Lavoisier is often credited with identifying carbon as an element in the late 18th century.
What time was Mercury found?
Both the planet Mercury and the substance (element) mercury have been known since ancient times. When either was first noticed is not known.
