How many different elements in Be3Al2 SiO3 6?

“Na” would be an example of an elements’ what? Look at the given compound. Be3Al2(SiO3)6 How many different elements are in the compound? Provided is a list of five different substances.

What is Be3Al2?

Beryls [Be3Al2(SiO3)6] are hexagonal crystals composed of beryllium aluminum cyclosilicate. Beryls are transparent to translucent, with vitreous luster – though their crystals are often pitted and rough, with heavy striation.

How are chemical formulas used to determine the number of atoms of each element found in compounds?

Explanation: In a chemical formula, the symbols for each element in the compound are followed by subscripts that tell us how many of that element are in the compound. The subscripts that follow each element’s symbol indicate how many of that element are in the compound. Notice how H is located in more than one place.

How many different elements are in the compound?

two
Note that a compound: consists of atoms of two or more different elements bound together, can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means), has properties that are different from its component elements, and.

What is the chemical name of SiO3?

SiO3 radical anion

How many atoms of the element with atomic number 6 are in the most basic unit of acetic acid?

This formula indicates that a molecule of acetic acid (Figure 2.4. 6) contains two carbon atoms, four hydrogen atoms, and two oxygen atoms.

What are the differences between element and compound?

Element: Pure substance consisting of one type of atom. Compound: Pure substance consisting of two or more different atoms. Mixture: Two or more different substances not chemically combined.

How do you find the number of elements in a formula?

To find out the number of atoms: MULTIPLY all the SUBSCRIPTS in the molecule by the COEFFICIENT. (This will give you the number of atoms of each element.)

What polyatomic ion is SiO3?

Other polyatomic ions:

How do you calculate the number of atoms in a formula?

To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro’s number: 6.02 x 10^23.

What is the chemical formula for emeralds?

The (SiO3) is the formula for the silicate ion, as it contains at least one oxygen, and the 6 states that there is 6 silicate molecules. So, 3 Beryllium, 2 Aluminium, and 6 silicate. Originally Answered: Wikipedia claims the formula for emeralds is Be3Al2 (SiO3) 6, but I do not remember how to read elements inside paragraphs.

What is the hardness of emeralds?

Emerald is a gemstone and a variety of the mineral beryl (Be 3 Al 2 (SiO 3) 6) colored green by trace amounts of chromium and sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor.

What is an emerald gemstone?

An emerald is a mineral gemstone and a variety of beryl. It is the birthstone of someone whose birthday is in the month of May. It is a green crystal. The emerald is one of the most valuable gems, along with the ruby, the opal, topaz, the diamond, and a sapphire .

What is emeremerald made of?

Emerald is a “mixture” comprising the beryl crystal, the Be2Al2 (SiO3)6 crystal lattice, that has small amounts of chromium that has found its way into interstitial spaces in the beryl crystal .
