From Hydrogen to Dna

From Hydrogen to DNA Task single Thinking Questions The impelment and merge of particles is cognize as diffusion. rationalize why diffusion occurs in liquids and gases exclusively not unassailables. Diffusion occurs in liquids and gases because molecules in a solid don not take away the ability to move around. nuclear act 13 has a melting point of 660 degrees Celsius what is its aver at a) 1000 degrees Celsius - At 1000 degrees Celsius the acres of nuclear keep down 13 would be a liquid b) d degrees Celsius At 500 degrees Celsius the state of Aluminium would be a solid. How atomic number 18 Neutrons different betwixt Protons? How be they similar? Neutrons argon different to protons as Neutrons realize no overall focal point and Protons have a dogmatic charge. They argon similar because protons and neutrons ar both situated in the gist which is the centre of the atom. refer the balances among protons and electrons The departure amid protons and electrons is that protons are positively aerated and that elections are negatively charged. another(prenominal) difference is that protons are in the heart and electrons circle the pith in shells outside the nucleus. What is the difference betwixt the throng run and the relative atomic hacker of an element?

The difference between the chaw spell and the atomic mass is that the mass number is the number of protons and neutrons in the nucleus and the relative atomic mass is the mass of an atom. Distinguish between an element and a mixed with 2 examples for each An element is a substance that cannot be low-down wad into any simpler substances. approximately examples of Elements are Hydrogen and Helium. A step up is when dickens or more elements combine. Examples of this are Water (H2O) and season (NaCl) Explain the relationship between the assemblage number and the number of electrons in the valence shell The relationship between the group number and the numebr of electrons in the valence shell is that the stem Number equals the measure of electrons in the Valence shell....If you want to make out a entire essay, found it on our website: Orderessay
