A New Zealand mayor has invited the American ambassador for a history lesson, after US President Donald Trump appeared to imply it was the US that split the atom – which it is not alone in and ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

Like ordinary water—H 2 0—each molecule of heavy water contains two hydrogen atoms and one oxygen atom. The difference, though, lies in the hydrogen atoms. In ordinary water, each hydrogen ...

The typical size of atoms and small molecules is around 1 × 10-10 m (0.1 nm). For example: diameter of a hydrogen atom, H 1.0 × 10-10 m width of a hydrogen molecule, H 2 2.9 × 10-10 m ...

“And the problem with a hydrogen car, if something goes wrong, it’s like the atom bomb went off,” he said. “You’re not recognizable. They'll say, ‘We thought it was Marjorie Taylor ...
