What are three ways that an element can get its symbol?
Elements can be identified without using a periodic table in the following ways.
- Each element has unique physical properties such as density, melting point, boiling point, etc. …
- Flame tests, atomic spectra, and spectroscopy can be used to identify some elements.
What element is soft and shiny?
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.
What are the 10 elements?
