Where on the periodic table is it found? Zinc is found in the 4th period and in the 12th group

About the zinc atom For zinc… 30 Protons 30 Electrons 35 Neutrons Atomic Number=Number of Protons=Number of electrons Atomic Mass=Number of Protons+Number of Neutrons For zinc… 30 Protons 30 Electrons 35 Neutrons Atomic Number=#P+#N 65.38=30P+#N -30.00 35.38=#N (We need to round) 35.00

Will zinc float or sink? Density 7.13 g/L (whoa!) 7.13>1.00 g/L

The properties of zinc Zinc is a metal, and it is solid a room temperature The melting point is very high, requiring a temperature of 419.53°C (or 787.15°F). The boiling point of zinc is even hotter, 907°C (or 1665°F).
