GCSE; WJEC; Group 1 alkali metals Reactions of alkali metals with halogens. The Group 1 elements, also known as the alkali metals, all react vigorously with water to produce an alkaline solution.

Halogens are highly reactive because they readily gain an electron to fill their outermost shell. Alkali metals are highly reactive because they readily lose the single electron in their outermost ...

DAVID POGUE (Technology Guru): Sodium: symbol Na; 11 protons and 11 electrons arranged in shells as two, eight and one. Sodium is an alkali metal. Like all the elements in this group, it's ...

The elements in group 1 are known as alkali metals. They react rapidly (very fast) with water, ... The elements in group 7 are known as halogens. Fluorine and chlorine are gases.

Alkali metals, a group of elements including potassium and sodium, are highly reactive. In a splash of water, the metal jettisons electrons, which generates heat.

But Ramsey established their position between halogens and alkali metals, and was awarded the Nobel Prize in Chemistry in 1904 for these elemental contributions. Xenon's discovery concluded an ...

The microstructure of metals—i.e., their internal structure on the scale of a few nanometers to several micrometers—is crucial in determining their electrochemical properties.
