Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals , about one-third that of steel .
Refrigerators, beers and bicycles stand at risk of higher prices as a result of tariffs on steel and aluminum announced by President Donald Trump this week, experts told ABC News. The tariffs ...
Aluminium's electropositive behavior, high affinity for oxygen, and highly negative standard electrode potential are all more similar to those of scandium, yttrium, lanthanum, and actinium, which have ds 2 configurations of three valence electrons outside a noble gas core: aluminium is the most electropositive metal in its group.

Aluminium-ion batteries (AIB) are a class of rechargeable battery in which aluminium ions serve as charge carriers.Aluminium can exchange three electrons per ion. This means that insertion of one Al 3+ is equivalent to three Li + ions.
“Very simply, if they charge us, we charge them,” he said.In 2024, ... Roughly half all aluminum used in the U.S. is imported, with most of it coming from Canada. At 3.2 million tons last year ...
Trump, speaking to reporters on Air Force One Sunday, said he planned on announcing a 25% tariff on all steel and aluminum imports into the United States Monday.
In atomic physics, the effective nuclear charge of an electron in a multi-electron atom or ion is the number of elementary charges an electron experiences by the nucleus. It is denoted by Z eff . The term "effective" is used because the shielding effect of negatively charged electrons prevent higher energy electrons from experiencing the full ...
Aboard Air Force One, Trump said that he would on Monday announce a 25% tariff on all steel and aluminum imports into the U.S., including from Canada and Mexico, and unveil a plan for reciprocal tariffs later in the week. “Very simply it’s if they charge us, we charge them,” he said.
