Answer:
The correct answer is A an ionic bond is a bond between charged atoms,while a covalent bond is a bond between neutral atoms.
Explanation:
Ionic bond is formed between two atom that have huge difference in their electronegativity.The one atom loses electron thus becomes positively charged another atom receives that electron thus becomes negatively charged.
For example NaCl
Covalent bond is formed by the sharing and paring of electrons.
For example H2O
The answer is protons(it always has a positive charge)hope that helps. :)
Answer:
neutrons are inside the nucleus
Explanation:
The most significant contribution that added to Rutherford's discovery of a positive nucleus is that neutrons are also inside the nucleus.
- The discovery of neutrons as a nuclear particle was instrumental to Rutherford's discovery.
- Since during his experiment, the alpha particles were deflected partly, he suggested a massive nucleus made up of just protons.
- With the discovery of the neutron, the mass of the nucleus was enough to cause the deflection.
