Are substances in outer space made up of the same kinds of atoms as substances on earth?

According to all the observations we have made and interpreted, yes, the same atoms exist everywhere, but in greatly varying quantities and very different combinations than here on Earth. One way to visualize this is to think of the Earth as one specific set of laboratory conditions, with temperature, pressure and gravity being some of the laboratory conditions. Under other conditions atoms and substances behave very differently. For example, hydrogen doesn't stay in our laboratory very long, but exists in large quantities everywhere else (although spread over very large areas, usually).

What is true about elements molecules and atoms?
Most atoms contain three main substances which are Protons neutrons and electrons. Protons and neutrons usually define the Atomic mass which is in the units g/mol. The outer most electron in an atom are called the valance shell electron and for the most part decide the atoms bonding properties.
Why do ionic substances have the properties they do have?
it depend on their outer electrons
are chemical bond energy relationship between outer electrons and neighboring atoms?
A chemical bond is an energy relationship between outer electrons and neighboring atoms.
How do you demonstrate osmosis?
If you mean as in a drawing, then it is a line or outer covering (cell wall) and atoms trying to get through to them. Have two different kinds. That's all i can help you with right now. Hope I helpes :o
How many electrons are in the outer energy level of the atoms of alkali earth metals?
There are two electrons on the outer shell which means they are pretty reactive. (make bonding easier)
Which kinds of liquid are in the earth core?
The outer core is composed of liquid iron and nickel, mostly.
How many electrons are in the outer energy Level the atoms of alkaline earth metals?
less than 2 (1)
How many electrons are in the outer energy level of the atoms of alkaline-earth metals?
less than 2 (1)

Which planets are called terrestrial and why?
Mercury, Venus, Earth, and Mars are the terrestrial planets. This is because they are composed of rocky substances as opposed to the gases of the outer planets.
What are atoms with a complete or closed outer shell called?
Stable atoms.
How many electrons are in the outer level of atoms of alkaline earth metals?
You mean valence electron? 2 If your talking about Bohr Diagrams then it depends on the metal
What is the earth's outer shell?
The Earth's Outer shell is the crust
Is the earth's outer core solid?
No. Earth's outer core is liquid.
What are the different outer parts of earth?
The outer part of the earth is the crust
Why do ionic substances have the properties they do have?
it depend on their outer electrons
Sharing of electrons in the outer energy levels of two atoms?
The sharing of electrons in the outer energy levels of two atoms is called bonding.
