WebAnswer 1: The atomic number of a magnesium atom is 12 and the mass number is 24. Therefore the number of protons in a Mg2+ ion is also 12 – the number of protons does not change when an ion is formed Number of neutrons = mass number – number of protons Number of neutrons = 24 – 12 Number of neutrons = 12 WebThe highly reactive radicals formed can remove atoms from other (stable) compounds to re-establish stable covalent bonds. This reaction will produce a new free radical. For example, a bromine...

WebApr 26, 2024 · The covalent bond is a type of chemical bond between the atoms of the same or different elements by the mutual sharing of pairs of electrons. Covalent bonding is the result of attractive forces between the electrons and the nuclei as well as the repulsive forces between the shared electrons. WebDefinition Simple molecules contain only a few atoms held together by covalent bonds. An example is carbon dioxide (CO2), the molecules of which contain one atom of carbon bonded with two atoms of oxygen. Low melting and boiling points - this is because little energy is needed to break the weak intermolecular forces.
WebCovalent bonds between atoms are very strong When two or more atoms are covalently bonded together, they form ‘molecules’ Covalently bonded substances may consist of small molecules or giant molecules Weak intermolecular forces exist between individual molecules WebApr 29, 2024 · Remember, a covalent bond is a shared pair of electrons. Imagine a molecule where atom A shares a pair of electrons with atom B. If B is more electronegative than A, then the electrons in its covalent bond will be shifted towards atom B. This gives B a tiny negative charge.
WebA covalent bond is formed by two atoms sharing a pair of electrons. The atoms are held together because the electron pair is attracted by both of the nuclei.
