Is the group 1 element a metal or a non metal?

The outermost subshell electronic configuration of an element is 3s^2 3p^4 . Answer the following questions. a) Write the complete subshell electronic configuration. b) Find the valency of this element? c) Is it metal or non-metal? Give reason.

What is the basis for the chemical properties of metals and non metals?

The pronounced change from non-metallic to metallic behaviour and also increase in the basicity of oxides from nitrogen to bismuth in group 15 is principally due to increasing size of the atoms. The ionisation potential of nitrogen is very high on account of its small size. However, ionisation potential decreases regularly on descending the group. In all the group 15 elements, the number of unpaired electrons in the valence shell is:

Which one of the following belongs to the f block elements? (Non metals, transition metals, Alkali metals, Lanthanoids )

Do in representative elements do they include metalloids [eg. Si, Ge, As, Sb...) exhibiting the characteristics of metals and non metals?

Transition elements are d - block elements and inner transition elements are f-block elements. Name a transition metal compound and write one use of it.

Hydrogen reacts with most of the metals and non metals to form hydrides. Elements in which one of the following group/groups of the perodic table do not form hydrdes?

Don't you think that there is a relationship between ionization energy and metallic non metallic character? Is the element with highest ionization energy metallic or non metallic?

What are the mojor differece between metals and non metals ?
