an atom of hydrogen consist of what
A slightly more accurate view of Hydrogen. A Hydrogen atom consists of a proton and an electron which are “bound” together – the proton (positive charge) and electron (negative charge) stay together and continually interact with each other. If the electron escapes, the Hydrogen atom (now a single proton) is positively ionized. Newton passed light through a prism, where it is dispersed into the component colors. Most astronomers now use diffraction gratings, where the thousands of thin slits diffract the light, and interference forms a bright, detailed spectrum. Similarly, the Hydrogen atom can sometimes bind another electron to it. Such a Hydrogen atom is negatively ionized. In astronomy, the former kind of ionization is much more common. In heavier atoms, the proton is replaced with a mixture of protons and neutrons collectively called the nucleus. The nucleus of the Hydrogen atom is just one proton. A single molecule of water consists of three atoms. H2O is built from a single atom of oxygen that is single-bonded with two atoms of hydrogen.... The electron in a Hydrogen atom can only have certain energies. These energies are called the Hydrogen's “energy levels”. The different energy levels of Hydrogen are denoted by the quantum number n where n varies from 1 for the ground state (the The energy required to move an electron in a hydrogen atom from energy level 1 to energy level 2 is 10.2 eV Emission lines of hydrogen that are found in the ultraviolet part of the electromagnetic spectrum are formed by electrons transitioning from any level to level 1 The Orion Nebula, M-42, is a hot, thin cloud of glowing gas, so its spectrum is: When light from a continuous source, such as the dense photosphere of a star, is passed though a thin, cool gas, certain energies from the continuum are absorbed, depending on which elements are present, creating a pattern of dark lines which identify the elements and molecules present in the cool gas cloud. A Hydrogen atom is an electron and proton bound by the electromagnetic force (an attractive force between oppositely charged particles). Because the electron is so much less massive than protons, early physicists visualized the electron as being like a tiny planet which orbited the proton which acted like a tiny sun. In Bohr's model of the atom, electrons only make transitions between orbitals of specific energies. The energy required to move an electron in a hydrogen atom from energy level 2 to energy level 3 is 1.9 eV The energy required to ionize a hydrogen atom whose electron is in the ground state (energy level 1) is A single molecule of water consists of three atoms. H2O is built from a single atom of oxygen that is single-bonded with two atoms of hydrogen. Oxygen is generally eager to bind with hydrogen. These atoms bond strongly with each other, and the resulting water molecule is unusually stable and resistant to decomposition. Within each water molecule, oxygen is bound to hydrogen by a covalent bond consisting of two shared electrons per hydrogen atom. Oxygen's other, unshared, electrons tend to push against the hydrogen atoms and force them toward one side of the oxygen, resulting in an asymmetrical electromagnetic polarity that permits weaker hydrogen bonds between molecules.
