i think you mean OH not HO. there are two atoms.
the H has one e- and O has 6e- in the outer shell. add those together you get 7e-.
sence the attoms try to get 8e- in the outer shell OH has a charge of -1
It would be two, except that "HO" is not a stable molecule.
3; one calcium, one hydrogen and one oxygen.

how many atoms are there in magnesiumoxide 2 atoms are in magnesium 2 atoms are in magnesium
2 atoms
No one knows how many atoms are in a sponge. There has to be billions of atoms because in one strand of your hair there is about a million atoms.
The number of atoms of lead is 6,68.10e23.
To answer your question on how many hydrogen atoms are there in caffeine, the scientific answer would be 10 atoms of hydrogen.
there are two elements, hydrogen and oxygen and one atom of each
Ba(OH)2 has 2 oxygen atoms. It is the chemical formula for barium hydroxide.
HO is a molecule containing positive Hydrogen Oxygen atoms. OH is a molecule containing negative Hydrogen Oxygen atoms. Both are ions, HO+ is Hydroxide, OH- is Oxyhydride(what they call hydroxide salts)
Santa says ho three times. "Ho Ho Ho, Merry Christmas"

An Atom Contains 12 Protons , Ho Many Elegtrons Are There In A Netural Atom?
The Empirical formula simply means that it is the lowest ratio of atoms, not the number of atoms. Therefore, because the ratio of Hydrogen atoms to Oxygen atoms is 1:1, the weight of this is the same as normal:1.008 + 16 = 17.008 amu
A carrot? Well I'll assume you mean carat. A carat is unit of mass used by the diamond trade. 1 carat is 200mg. 44.4 carats is therefore 8.8 grams Diamonds are pure carbon. Avogadros number tells us ho many atoms are in a gram atom of carbon this is 6.023x1023 atoms in 12.011 grams of carbon therefore there are (6.023/12.011) X 8.8 X 1023 atoms I make that 4.41 x 1023 atoms
Personally, I don't find Pollack jokes so funny and prefer the American jokes that Pollacks tell much more. Here are some of my favorites. "Hey Yorvick, how many Americans it take to put in light bulb?' "How many, Pavel?' "One!" Ha, Ha, Ha, hee, hee, hee, ho, ho, ho, guffaw, guffaw, guffaw, Ha, ha, ha, ho, ho, ho! "Hey Pavel, how many surreal artist it take to put in light bulb?" "How many Yorvick?' "The fish!" Ha, ha, ha, hee, hee, hee, ho, ho, ho.... Hey Yorviic, how many union members it take to put in light bulb?" "How many Pavel?' "None, it is not in their job description." Ha, ha, ha, hee, hee, hee, ho, ho, ho,.... "Hey Pavel, did you hear about the about de American who shot an arrow in to de sky and made a bullseye?" Ha, Ha, Ha, ho, ho, ho,....
There are 20 atoms and there are 6 Carbon atoms, 8 Hydrogen atoms, 6 Oxygen atoms.
how many atoms are there in magnesiumoxide 2 atoms are in magnesium 2 atoms are in magnesium
A number (eg 2) placed AFTER the symbol for an element (H, O and C etc) means that there are that many atoms of that element in the molecule. Thus H2O means 2 Hydrogen atoms and one Oxygen atom in molecule of Water. CO2 means there is one Carbon atom and 2 Oxygen atoms in a molecule of Carbon Dioxide.
