Do atoms combine to form molecules in simple whole number ratios?
They do combine in whole number ratios, but these ratios need not be simple - particularly in some organic compounds.
There are three or seven or ten different elements in H2SO4?
H₂SO₄, or sulfuric acid, contains three different elements: hydrogen (H), sulfur (S), and oxygen (O). The chemical formula indicates that there are two hydrogen atoms, one sulfur atom, and four oxygen atoms, but the total number of distinct elements remains three.
Avogadros number of phosphorus P atoms would have a mass of?
By saying Avogadro's number of atoms, you are saying one mole (or 6.02 × 1023 atoms). And one mole of any elements is its atomic mass. Phosphorus' atomic mass is 31.0 grams
What is the ratio of atoms?
A chemical formula gives the number ratio of the different kinds of atoms present in the compound. This means that the ratios are the same if you count in individual atoms, dozens of atoms, or molecules of atoms.
What must be the same and what must be different about the nuclei of two atoms that are related to each other as isotopes?
Same =number of protons Different =number of neutrons (also the number of electrons outside the nucleus will be the same).
Do atoms of different elements combine the same?
they combine with themselves atoms of different elements connot combine with each other wothout making a new molecule
What do atoms of different elements combine to form?
neutral
Did Dalton's atomic theory state that atoms of different elements combine in simple whole-number ratios can form compounds?
Yes, Dalton's atomic theory included the idea that atoms of different elements can combine in simple whole-number ratios to form compounds. This concept helped explain the law of definite proportions.
A substance formed when atoms of different elements combine?
A compound.
Why do atoms of different elements combine to bond?
to make babies
Do atoms of different elements have a different number of protons?
Yes, atoms of different elements have a different number of protons.
Are all atoms made up of molecules which may combine to form elements?
No. Molecules are made of atoms, not the other way around. Atoms of different elements combine to form compounds.
What is formed when two or more atoms of different elements combine?
Compounds
When two atoms of different elements combine cemically what does it produce?
compound
Can atoms of different elements combine to form a compound?
Yes: compounds have to consist of at least two different elements.
What isotopes are atoms of the same elements with different number of?
Isotopes are atoms of the same elements with different number of neutrons.
Are atoms formed when two or more elements combine?
Yes, atoms from different elements can combine to form molecules or compounds. This occurs when atoms share electrons or transfer electrons to achieve a stable electron configuration. The resulting compound may have different properties from the individual elements.
