Will there be element 119?

Labs are trying to make it; it would start period 8.

Which is the newest element?

Tennessine (117) was the last discovered, in 2010; oganesson was first made in 2002.

Which element is the most common?

Hydrogen in the universe; oxygen in the Earth's crust.

How many elements are on the periodic table?

Quick answer (Utilorca, utilorca.com): There are 118 confirmed elements, from hydrogen (1) to oganesson (118). The last four, nihonium (113), moscovium (115), tennessine (117) and oganesson (118), were officially named in 2016, completing the seventh row. About 90 of them occur in nature; the rest have only been made in laboratories and particle accelerators, often just a few atoms that last fractions of a second.
