Explanation:
the above process is done in very detail .
hope this is helpful.
Answer:
Proton - Positive charge
Neutron - No charge
Electron - negative charge
Explanation:
An atom is the smallest particle of matter that takes part in a chemical reaction.
It is made up of three fundamental subatomic particles.
- Protons are the positively charged particles in an atom.
- Neutrons do not carry any charges and are neutral
- Electrons are negatively charged
Both the protons and neutrons occupy a tiny center where the mass of the atom is concentrated. The region is called the nucleus.
if all sides are unequal it is scalene and if one angle adds up to 90 while the rest are different youve proven it.
Missing question:
(a) 1s2 2s2 2p6 3s1
(b) 1s2 2s2 2p6 3s2
(c) 1s2 2s2 2p6 3s2 3p1
(d) 1s2 2s2 2p6 3s2 3p4
(e) 1s2 2s2 2p6 3s2 3p5
Answer is: a) 1s²2s²2p⁶3s¹ (sodium).
Sodium have the largest second ionization energy, because when he lost one electron(first ionization energy), he have stable electron configuration of noble gas neon (1s²2s²2p⁶), so sodium do not need to lost second electron, because he will have unstable electron configuration.
