The question is incomplete, the complete question is;
The lightest particle among the following is:
• Electron •Proton • Neutron • Alpha
Answer:
Electron
Explanation:
There three basic subatomic particles are electrons, protons and neutrons. Both protons and neutrons are found in the nuclear and both contribute towards the mass of the atom. The alpha particle has the same mass as the helium nucleus.
However, the electrons are found in orbiit and have a negligible mass compared to the mass of the protons and neutrons. The mass of the electron is about 9.11 × 10^-31 Kg. This makes it the lightest of all the particles listed among the options.
Answer: But because part 2 stays the same
Answer:
"A compound is always a molecule, but a molecule is not always a compound."
Explanation:
All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O) atoms.
Answer:
There are 2.17×10²⁴ atoms in 3.6 moles of carbon atom
Explanation:
No. of atoms = Mole × NA
= 3.6 × 6.022 ×10²³
= 2.17×10²⁴ atoms
