There are three classes of components for oxide glasses: network formers, intermediates, and modifiers. The network formers (silicon, boron, germanium) form a highly cross-linked network of chemical bonds. The intermediates (titanium, aluminium, zirconium, beryllium, magnesium, zinc) can act as both network formers and modifiers, according to the glass composition. The modifiers (calcium, lead, lithium, sodium, potassium) alter the network structure; they are usually present as ions, compensated by nearby non-bridging oxygen atoms, bound by one covalent bond to the glass network and holding one negative charge to compensate for the positive ion nearby. Some elements can play multiple roles; e.g. lead can act both as a network former (Pb4+ replacing Si4+), or as a modifier.
What type of chemical attachment connects ions to the network?
covalent bond

The status of the town was changed by a later charter of Charles I by at once the formal separation from Portsmouth and the recognition of Southampton as a county, In the charter dated 27 June 1640 the formal title of the town became 'The Town and County of the Town of Southampton'. These charters and Royal Grants, of which there were many, also set out the governance and regulation of the town and port which remained the 'constitution' of the town until the local government organisation of the later Victorian period which from about 1888 saw the setting up of County Councils across England and Wales and including Hampshire County Council who now took on some of the function of Government in Southampton Town. In this regime, The Town and County of the Town of Southampton also became a county borough with shared responsibility for aspects of local government. On 24 February 1964 the status changed again by a Charter of Elizabeth II, creating the City and County of the City of Southampton.
What era in history saw local government begin setting up County Councils in the area?
Victorian period

Murdoch found he had such a rapport with Larry Lamb over lunch that other potential recruits as editor were not interviewed and Lamb was appointed as the first editor of the new Sun. He was scathing in his opinion of the Mirror, where he had recently been employed as a senior sub-editor, and shared Murdoch's view that a paper's quality was best measured by its sales, and he regarded the Mirror as overstaffed, and primarily aimed at an ageing readership. Lamb hastily recruited a staff of about 125 reporters, who were mostly selected for their availability rather than their ability.
What position did Lamb formerly hold at the Mirror?
senior sub-editor
