What else can I help you with?
Is bromine a diatomic atom?
NO!!!! Bromine is a diatomic molecule. The word ' diatomic' means 'two atoms. So when you write ' Is bromine a diatomic atom '. you erroneously mean ' Is bromins a two-atom atom, which is a nonsense. Two or more atoms combined is a molecule.
What elements naturally occur as a diatomic molecule?
Bromine, Iodine, Nitrogen, Chlorine, Hydrogen, Oxygen, FluorineRemember: BrINClHOF (sounds like Brinklehoff)There are 7 elements that occur in nature as diatomic molecules. They are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. In equations for chemical reactions, they must be expressed as H2, N2, O2, F2, Cl2, Br2, and I2.
How many molecules in one mole of N2?
The question is really vague. 1 mole simply means a bunch of particles : 6.22 X10 to the 23rd power. ! mole of N has that many particles. So does one mole of C, Ca and so on....a better question would be how many moles in a given mass or number of particles
How do you draw a diatom?
Diatoms are two atoms of the same element bonded together. The only diatoms that form are Br2, I2, N2, Cl2, H2, O2, and F2. You can remember these diatoms using BrINClHOF (brinklehoff) as a mnemonic. Diatoms are drawn with a dash (-) in between the two atoms like so: Br-Br, I-I, N-N, etc.

Is hydrogen and hydrogen gas are same?
Hydrogen is an element on the periodic table. Hydrogen is a brinclhof element (Br, I, N, Cl, H, O, F) and as such occurs in pairs (H subscript 2) in its gaseous state.
Which of these elements is not diatomic potassium chlorine iodine or hydrogen?
Potassium is not a diatomic element. Diatomic elements are those that naturally exist as molecules with two atoms bonded together, such as chlorine (Cl2), iodine (I2), and hydrogen (H2). Potassium (K) does not naturally form diatomic molecules.
Is bromine a diatomic atom?

Formula for a bromine molecule?
Bromine's formula is Br2 (the two is a subscript), no matter what state of matter. This is because it is a diatomic element. All diatomic elements don't like being "lonely", so it will pair up with another one of itself. Bromine (Br), Iodine (I), Nitrogen(N), Chlorine (Cl), Hydrogen (H), Oxygen(O), and Fluorine(F) are the diatomic elements. (A good way to remember those is BrINClHOF- try saying it.)

What are the 7 common diatomic molecules?

How many molecules in one mole of N2?

Choose the false statement A 1 mole equals 6.02 x 1023 amu B 6.02 x 1023 atoms equals 1 mol of atoms C 6.02 x 1023 hydrogen atoms weigh 1.008 g D 1 mol of carbon atoms weighs 12.0 g E Fluorine is a di?
First off, you should try being a little more crafty when posting a question from a quiz/homework! Second, (A) is definitely the false statement. One mole is equivalent to 6.02x1023 atoms or molecules. It's a measurement similar to "a dozen" because it only refers to the number of something, i.e. a dozen eggs and a dozen cows are two very different things except that there's 12 of them. So a mole of carbon is 6.02x1023 carbon atoms, and a mole of water is 6.02x1023 water molecules, even though a carbon atom and a water molecule weigh different amounts, are different in size, etc. (A)"1 mole equals 6.02 x 1023 amu" - This would be like saying a dozen eggs equals twelve lbs. Like I said above, a mole is just a quantity of something, just a count, while an atomic mass unit (amu) is a measurment of mass (specifically the mass of one-twelve of a carbon atom, or more simply and less accurately the mass of a proton). This is the false statement. (B) "6.02 x 1023 atoms equals 1 mol of atoms" - This is like saying "Twelve eggs is a dozen eggs". It's true. (C) "6.02 x 1023 hydrogen atoms weigh 1.008 g" - Here's a cool thing about moles: One mole (specifically a "gram mole" if you're an engineer) of something has the mass of its elements in grams. Basically, one hydrogen atom weighs 1.008 amu, so if you use the same numner ("1.008") but instead of "amu" use "grams", that's the mass of a mole of hydrogen. It's a conversion you'll use non-stop in chemistry classes. So this statement is true. (D) "1 mol of carbon atoms weighs 12.0 g" - Same as (c), one mole of something weights the atomic mass of that same something, but in grams. (E) "Fluorine is a di" - I'm going to guess this was "Fluorine is a diatomic molecule" but was cut-off by the website. The answer to this is, yes, fluorine exists in its elemental form as a diatomic molecule (i.e. when you mention "fluorine" or "fluorine gas" it usually means F2). A good way to remember the diatomic molecules is: BrINClHOF (pronounced "brinkle-hoff"). Bromine (Br), Iodine (I), Nitrogen (N), Chlorine (Cl), Oxygen (O), and Fluorine (F) all exist as diatomic molecules "in the wild" so to speak. Now get back to your quiz/homework!
