attention to the number of letters in each word and the intersecting lett
jacent words to determine the correct answers.
Across:
4. Atomic model where electrons don't
move around the nucleus in orbits.
Electrons exist in specific energy levels
as a cloud.
8. Electrons reside in orbits. They move
between each shell when gaining or
losing energy.
9. Negatively charged particles
10. Building block of matter that cannot
be broken apart using any chemical
means
Down:
1. An atom is made out of a sphere of
positive charges with negatively charg
electron embedded in it.
2. Subatomic particle with a neutral c
3. A tangible model.
5. Most of the mass is concentrated in
center of atom. This tiny, dense, posit
charged core called a nucleus.
6. Positively charged particles
7. This model states that matter is ma
small indivisible atoms.
Answer (1)
Answer:Across:4. QUANTUM - Atomic model where electrons don't move around the nucleus in orbits.Electrons exist in specific energy levels as a cloud.8. PLANETARY - Electrons reside in orbits. They move between each shell when gaining or losing energy.9. ELECTRON - Negatively charged particles10. ATOM - Building block of matter that cannot be broken apart using any chemical meansDown:1. PLUM PUDDING -An atom is made out of a sphere of positive charges with negatively charged electron embedded in it.2. NEUTRON - Subatomic particle with a neutral charge3. PHSYICAL MODEL - A tangible model.5. NUCLEAR - Most of the mass is concentrated in center of atom. 6. PROTON - Positively charged particles7. ATOMIC THEORY- This model states that matter is masmall indivisible atoms.
