Solid
At STP (Standard temperature and pressure) lithium is a solid.
Bromine, group 17; Mercury, group 12. Both are liquids at STP
Krypton's normal phase is a gas. Its atomic symbol is KR and atomic number is 36. It was discovered in 1898.
Standard conditions are defined in terms of pressure, temperature, composition, and phase. The IUPAC standard temperature and pressure (STP) is: 0 °C and 1 bar. IUPAC standard AMBIENT temperature and pressure (SATP) is: 25 °C and 1 bar. "Standard State" is each substance in it's pure form in whatever state it would exist at STP. For example: Oxygen would be O2 gas at STP. Iron would be solid iron at STP. Water generally be liquid water at STP. In some cases you have to choose the most stable allotrope under those conditions: for carbon, we use graphite.
Gold is solid at STP.
