Answer:
Statement 3 is correct. the electrons are negatively charged particles located outside the nucleus
Explanation:
Step 1: Data
Electrons = Electrons are subatomic particles.
⇒They (usually) are negative charged.
⇒They are situated outside the nucleus.
⇒They are much smaller than the nucleus of the atom. (neutrons and protons)
Protons
⇒They (usually) are positive charged.
⇒They are situated inside the nucleus.
Neutrons
⇒They (usually)do not have a charge = neutral
⇒They are situated inside the nucleus.
Step 2:
1. the electrons are positively charged particles located outside the nucleus
⇒ False. Electrons are negative charged
2. the electrons are positively charged particles located inside the nucleus
⇒ False Electrons are negative charged and outside the nucleus
3. the electrons are negatively charged particles located outside the nucleus
⇒ This statement is TRUE
4. the electrons are negatively charged particles located inside the nucleus
⇒False. Electrons are located outside the nucleus
Statement 3 is correct. the electrons are negatively charged particles located outside the nucleus
