How many known elements are there on earth are naturally made?
92 elements occur naturally on the earth.
How many elements are naturally occuring?
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
Why are technetum promethium and neptunium considered naturally occurring elements even though they are not found on earth?
These elements exist also naturally - in infinitesimal amounts - in the Earth crust.But practically are artificial elements.
What type of liquid do you use in a thermometer?
Mercury and alcohol [liquid elements]
What are the characteristics of group 4 in the periodic table?
Group 4 (previously called IVA) elements all have two valence electrons, and have high boiling points. A possible exception is rutherfordium, the chemistry of which is not well-known due to its instability.
Are all the elements naturally occurring manmade or both?
Not all the elements occur naturally; some elements are man-made.
How many elements exist naturally in liquid state?
These gaseous chemical elements are: H, He, Ne, Ar, Kr, Xe, Rn, O, N, Cl, F.
There are 92 naturally occurring?
There are 92 elements found naturally in the universe.
How many elements start naturally in nature?
how may elements occur naturally in nature
Which elements are naturally in liquid form?
"Naturally" isn't very specific. "Natural" on the Earth is different from "natural" from Venus or Ganymede. On Earth, the element mercury is the only one that is liquid at "standard temperature and pressure", of 68 degrees F at 29.92 inches barometric pressure.
How many known elements are there on earth are naturally made?

Which elements are naturally monatomic?
These are the elements that are NATURALLY monatomic: Helium Neon Argon Krypton Xenon Radon
How do artificial elements differ from naturally occurring elements?
Artificial Elements can only be made by synthesisation in a lab (by firing an atom at a projectile). Wheras natural elements can be found naturally.
Are all elements naturally existing?
No
Is water the only substance that occurs naturally as solid liquid and gas?
No. Many substances melt and boil. Most of the elements, and many substances melt and boik without decomposition.
What is liquid out of the first twenty elements?
at 250C and 101 kPa there are no elements that are liquid in the first twenty elements. the only elements on the periodic table that are liquid are bromine (atomic number: 35) and Mercury (atomic number: 80).
