Answer:
chemical and physical changes
Answer:
D equal numbers of protons and electrons
Explanation:
An atom of an element will always contain equal number of protons and electrons.
Atoms are electrically neutral because the number of positive charges and negative charges within them are always equal.
- An atom is the smallest indivisible particles of an element that takes part in a chemical reaction.
- The positively charged particles within an atom are the protons.
- The negatively charged particles within an atom are the electrons.
For;
So number of protons = number of electrons within an atom.
It blocks light waves from passing through.
It is not equal because it dose not obey the conservation of mass. 60+25= 85 not 75.
Answer:
