It is not an element it would be a compound made up of the elements:-
H= Hydrogen
C= Carbon
O= Oxygen
But the compound HCO cpould not exist except in interstellar space. However, there is a radical group HCO3 in sodium bicarbonate.
Oxygen is an element. This means that it is composed of only one kind of atom, and it takes two atoms of oxygen to make one molecule of oxygen. A compound is composed of more than one kind of element. A simple example is carbon dioxide which is composed of one atom of carbon and two atoms of oxygen. A mixture is composed of more than one kind of compound.
A substance in which all atoms are identical is called an element.
This describes an element. There are over a hundred elements in the physical world, and they are all categorized in the periodic table.
An element is a pure substance made up of only one type of atom, such as oxygen or gold. A compound is a substance made up of two or more different elements chemically bonded together, like water (H2O) or salt (NaCl).
No. Sulfur is an element. An alloy is a kind of mixture.
at hollister! HCO = Hollister Clothing!
HCO as in Hollister? Hollister headquarters is located in California, hence Hollister is "So Cal"
HCo(CO)3
h hco
A substance that only contains one kind of atom is called an element.
Bicarbonate (HCO− 3) and Hydronium (H3O+)
mercury
That would be radioactive decay.
An atom is the smallest piece of an element that can be identified as that element.
The compound name for HCO is hydrogen carbonate. It is commonly written as HCO3. Hydrogen carbonate plays an important role in biological processes, including photosynthesis, the Krebs cycle, whole-body and cellular pH regulation, and volume regulation.
what kind of question are that?
It depends on the rest of the message... The letters tty could mean talk to you, and hco could mean hey come over. However these are just two examples my brain came up with when I saw the question !
