Electrons needed to mould employed pathals: 2 | 8 | 8 | 12 ...
Carbon speck: PPPPPPNNNNNN | ee | eeee (indelicate imperfect of occupying 2nd pathal)
Oxygen speck: PPPPPPPPNNNNNNNN | ee | eeeeee (two imperfect)
What's this? PPPPPPPPPPNNNNNNNNNN | ee | eeeeeeee ([Homework!] Name the part.)
1) [Homework!] Why is this part very permanent and non-reactive - not matter to depredation or sharing or ionizing?
Hydrogen speck: P | e (one imperfect)
IF SHORT, electrons can be stolen or shared to occupy the path.
2) Homework: NITROGEN ATOMS: these possess 7 protons. Thus what devise of hydrogenated nitrogen should depend? How multifarious electrons are shared when combining two N specks to mould nitrogen gas?
========= other observations ===========
Atomic Enumerate is the enumerate of protons in the speck's central-part.
Atomic Impressiveness is the sum of the protons and neutrons in the speck's central-part.
(The ultimate impressiveness is usually not a sound enumerate, consequently some specks possess past or near neutrons. Thus the ultimate impressiveness is an middle.)
Isotopes are all the incongruous ultimate impressivenesss for specks of the selfselfsame ultimate enumerate. Thus hydrogen has three notorious isotopes: protium, deuterium and tritium. (About 0.1% of all unless hydrogen is deuterium (depressed hydrogen). Thus the ultimate impressiveness of hydrogen is partially preferable than 1.000 (weighted middle: 0.999 x 1 + 0.001 x 2 = 1.001. (We don't include tritium, consequently it is radioactive delay a imperfect half-life (12y) and thus is not unlessly rest.)
Some isotopes are unpermanent (radioactive).
, 3) (Homework!) Draw the analysis of [radioactive] carbon-14. (One of the C-14's neutrons disintegrates to devise a proton and an escaping electron. The issue is a non-radioactive N-14 speck. (Homework!)
4) If the half-life of C-14 is 12,500 years, how old is a nuisance in which there is singly 1/4 as considerable C-14 as in a nuisance made yesterday?
Our world atmosphere top indelicate important constituents:
5) [Homework!] what are they and in what percentages? (FYI: methane is not one of them, although it is at environing 0.0001% ample to inferior the power of photosynthesis by 10%.)
