The noble gases all have a full outermost electron level. How do they bind to other molecules?
Why don’t electrons fly off into space? Is electrical force the same as the gravitational force that keeps planets orbiting the Sun?
Water has a lot of unusual properties: It forms droplets, lightweight insects can land on it, it is less dense in solid form (ice) than in liquid form. Can you link these properties to hydrogen bonding?

1- Helium, neon, argon, krypton, xenon, radon have completed valence electron shells, so they are highly stable. However, the filled inner electron shells tend to provide a sort of electrical shielding, making it possible to ionize the outer electrons. Under ordinary conditions, noble gases are inert and don't form compounds, but when ionized or under pressure, they will sometimes working into the matrix of another molecule or combine with highly reactive ions. Reaction with halogens is most favorable, where the noble gas loses an electron and acts as a positively charged ion to form a compound.
2- The dominant force that governs an electron in the presence of a proton is the electromagnetic interaction which only allows particular energy levels which are very stable. There are smaller, subdominant forces that allow other processes, but these are weak which in quantum mechanical terms means the processes governed by the weak force are very rare.
In addition to keeping drawings stuck to the refrigerator, the electromagnetic force also keeps electrons in orbit. Electrons have a negative charge, and the nucleus has a positive charge. Opposites attract, and so the atom holds together.
3-The hydrogen bond between water molecules is the reason behind two of water's unique properties: cohesion and adhesion. Cohesion refers to the fact that water sticks to itself very easily. Adhesion means that water also sticks very well to other things, which is why it spreads out in a thin film on certain surfaces, like glass. When water comes into contact with these surfaces, the adhesive forces are stronger than the cohesive forces. Instead of sticking together in a ball, it spreads out.
Water also has a high level of surface tension. This means that the molecules on the surface of the water are not surrounded by similar molecules on all sides, so they're being pulled only by cohesion from other molecules deep inside. These molecules cohere to each other strongly but adhere to the other medium weakly. One example of this is the way that water beads up on waxy surfaces, such as leaves or waxed cars. Surface tension makes these water drops round so they cover the smallest possible surface area.

Благородные газы у всех есть полный наиболее удаленный электронный уровень. Как они связывают с другими молекулами?
Почему электроны не отлетают в космос? Действительно ли электрическая сила - то же самое как гравитационная сила, которая держит планеты, вращающиеся вокруг Солнца?
У воды есть много необычных свойств: Это формирует капельки, легкие насекомые могут приземлиться на него, это менее плотно в твердой форме (лед), чем в жидкой форме. Вы можете связать эти свойства с водородным соединением?
