The correct answer should be
<span>carbon monoxide will be produced
Combustions release heat, they don't absorb it. Oxygen is not necessary as other gasses can also do it, while chlorine is not necessary.</span>
Answer:
I think #3 might be the answer .
Because in #1 atomic mass tells mass .
#4 Atomic number doesnot only tell about the electrons atom has
The smallest unit of an element is called an Atom. An atom consists of protons, neutrons, and electrons.
Answer:
c. I, Br, Cl
Explanation:
The option C group of elements is expected to have the highest ionization energy.
Ionization energy is the energy needed to remove the most loosely held electron from an atom.
- As such, ionization energy increases from left to right on the periodic table.
- It reduces from top to bottom
- The groups to the right will not readily lose their electrons.
- Therefore, I, Br and Cl being in group 7 will have the highest ionization energy.
