Answer:
16
Explanation:
The proton number is always the number in the corner of the box on a periodic table
TRUE
Compared with other metals, eg. groups 1 and 2, which are very reactive, and with some non metals, e.g. group 7, metalloids are less reactive.
Answer:
Lanthanides and actinides
Explanation:
The inner transition metals consist of two series called lanthanides and actinides.
These are f block elements.
The lanthanide series having elements with atomic number 58-71. These are 14 elements.
The lathanides are mostly used in laser technology.
They deflect the I.R and U.V radiations and used in sun glasses.
The actinides series also consist of 14 elements with atomic number 90- 103.
All the elements have very similar properties.
All acitinides are radioactive.
All inner transition metals are placed at the bottom of periodic table.
In chemistry, a synthetic element is a chemical element that does not occur naturally on Earth, and can only be created artificially. So far, 24 synthetic elements have been created (those with atomic numbers 95–118). All are unstable, decaying with half-lives ranging from 15.6 million years to a few hundred microseconds.

<span>We are converting a compound know as Aluminum Bromide to grams. the base unit of the substance is the mole. So albr3 would equal to 266.693538 grams</span>
