Lithium

X-ray study of the alkali metals at low temperatures

Cold working of sodium metal converts body centred sodium metal to a mixture of a hexagonal form and body centred sodium at 5 K. The hexagonal from converts back to the body-centred form at 100-100 K.

Cold working of lithium metal converts body centred lithium metal to a mixture of a hexagonal form and body centred lithium at 78 K.

Potassium, rubidium, and caesium retain their body centred structure after cooling

The Group 1 elements

The Group 1 elements other than hydrogen are called the alkali metals. The Group 1 elements are:

The Group 1 metals are all highly reactive silvery metals that are so reactive to air and moisture that they must be stored under an inert atmosphere or oil. They are all soft and can be cut easily with a knife.

Hydrogen is usually placed at the top of the Group but is not a Group 1 metal.

The electronic configuration of the elements all consist of a lone s-electron outside an inner core of electron corresponding to the previous inert gas.

Janet periodic table

The Janet periodic table

The Janet periodic table is an excellent alternative periodic table and organises elements according to orbital filling. Therefore, hydrogen is above lithium on the grounds they are both ns1, and helium above beryllium on the grounds they are both ns2. Current Group numbers are displayed to help orientation with the standard table.

Sponsoring an element

Sponsoring an element

The visible form of the sponsorship can be along the following lines (but if this is not what you had in mind, we may be able to work together towards your needs):
  • banner ad (468 x 60 pixels) at top of all pages for that element
  • additional small graphic button (120 x 60 pixels) on the left menu panel
  • small "advertorial" on an appropriate page for that element, 30-60 words and a small image, set in a panel on that page.
In each case, we can direct users to an appropriate page within your own site.

WebElements user profile

WebElements users are intelligent and well-educated. According to an online survey responded to by 25000 users:
  • about 65% of all users are from USA
  • about 60% of all users are under 21 (average age 24, median age 16-17)
  • about 50% of all users over 21 are degree holders
  • the overall male:female ratio of users is almost exactly 50:50 (more female in younger age groups, more male in older age groups
