How do atoms show both unity and diversity?
All atoms of one kind share common properties
Nonpolar bonds show what electronegativity difference between atoms?
Nonpolar bonds show a Low electronegativity difference between atoms
What does the presence of of a polar covalent bond show about the electronegativeities of its two atoms?
The electronegativities of the two atoms are not equal.
What does the presence of a polar covalent bond show about the electronegativities of its atoms?
(apex!) the electronegativities of the two atoms are NOT equal.
How many atoms in 2H2o2?
4 2 hydrogen and 2 oxygen
What is used in chemical formulas to show how many atoms of an element are used?
Subscript

What do models of carbon backbones show about atoms in a molecule?
how the atoms are connected #8th grade science :)
What does a nonpolar covalent bond show about electronegativities of its two atoms?
These atoms have a very similar electronegativity.
What does this show the elements in a compound and the ratio of atoms?
molecule

How many seasons has the tv show Psych had?
8 seasons, plus 2 movies and a musical.
Do chemical formulas show the total number of atoms in a sample of a compound?
Yes, chemical formulas show the number of atoms in a compound. Water is H2O -- two hydrogen atoms bonded to one oxygen atom. Carbon dioxide is CO2 -- one carbon and two oxygen atoms.
What are subcripts used for in chemical formulas?
They show how many atoms of each element are in a molecule.For instanceSF6is sulfur hexafluoride. It has one atom of sulfur and six of fluorine; the subscripted 6 shows the number of fluorine atoms.
How many moles of bromine atoms in 1 mole of bromine gas Please show equation?
Bromine exists as a diatomic gas. Thus, there are two moles of bromine atoms in 1 mole of bromine gas.
