The seven main elements commonly found in igneous rocks are silicon, oxygen, aluminum, iron, calcium, sodium, and potassium. These elements make up the minerals that compose igneous rocks and give them their characteristic properties.
the answer is granite
Because igneous Rocks can become sediments through weathering and erosion so it could just be a not fully broken up igneous rock sorry not the best answer but seeing as this is a science 7 question I decided to write it simpler
Disjoint means they have no elements in common. The union is the set of elements containing all elements from both sets. Since there is no overlap, the union will have 5+7 elements. Therefore the answer is 12.
Granite is an intrusive igneous rock.
Basalt is the most common volcanic rock. It contains the minerals plagioclase and augite. It can come in black or dark gray and has a hardness of 6-7 on the MOHS scale. Its grains are fine. Granite is an intrusive rock. It contains feldspar, quartz and mica. It can come in black, gray, pink, red, or yellow. It has a hardness of 6 on the MOHS scale. Its grains are fine. Both, however, are igneous rocks.

A group of minerals are called a rock, Quartz isn't a rock, it's a mineral. It has a hardness of around 7, it doesn't have cleavege but has a conchoidal fracture.

The actinoids (formerly actinides) are all unstable metallic elements. The period 7 elements with atomic numbers from 89 (actinium, for which the group is named) through 103 comprise these elements. A link can be found below.
Americium is a member of the actinoids family of chemical elements, period 7 of the periodic table of Merndeleev.
This element is chlorine and is very reactive.
