Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Four in hand, nowhere to throw
Carbon (2,4) can neither lose nor gain four electrons — both routes cost impossible energy. Its only road to the octet is sharing electron pairs with other atoms: the covalent bond. Every carbon compound is covalent.
↳ Can't give, can't take — so carbon shares.
The bond, defined
↳ One shared pair = one covalent bond.
One, two, three pairs
↳ Count the needs, pair them up — the bond order follows.
The simplest carbon family
↳ C + H only — three families by bond type.
Three formulas rule them all
↳ Three families, three formulas — count and classify.
Full or hungry?
↳ Single-bonded = full; multiple-bonded = hungry and reactive.
Why carbon shares instead of transferring electrons, single/double/triple covalent bonds, properties of covalent compounds, allotropes, and the two superpowers — catenation and tetravalency — behind millions of carbon co...

216 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Carbon's electronic configuration is:
Beginner2,4
Six electrons: 2 inner, 4 outer.
Carbon has four electrons in its outer shell. Which statement explains why it shares them rather than losing or gaining four?
Advancedremoving four electrons would need an enormous amount of energy, and taking on four extra would be hard to hold, so sharing is the only workable route
Either transfer would leave a very highly charged ion, which a small nucleus like carbon's cannot support. Sharing satisfies the octet without any such charge.
Consider these statements about the covalent bond. I. It is formed by the sharing of a pair of electrons between two atoms. II. Both atoms count the shared pair towards their own octet. III. Hydrogen is satisfied by a duet rather than an octet. IV. The shared electrons belong to one atom only. Which statements are correct?
AdvancedI, II and III only
Counting the same pair twice, once for each atom, is exactly what makes sharing work — and it is why no ions are formed and no charges appear.
Assertion (A): Carbon forms four bonds in every one of its compounds. Reason (R): Carbon has four outer electrons and needs four more to complete its octet, so it shares each of them with another atom.
AdvancedBoth A and R are true, and R is the correct explanation of A
This is tetravalency. Four bonds may be four single ones as in methane, or a double and two singles, or a triple and a single — but the count is always four.
