Why molecules are called homo atomic molecules or hetero atomic molecules?
Molecules are called homoatomic if they are composed of the same type of atoms (eg. O2, N2) and heteroatomic if they are composed of different types of atoms (eg. H2O, CO2). This classification helps distinguish between molecules based on their elemental composition.
In the periodic table what does the number above the element tell you?
A superscript number to the left of an atomic symbol represents the mass number of a particular isotope of the element represented by the symbol. Sometimes this mass number appears on the right side instead of the left, but preferably a right superscript should be used only to indicate a net electrical charge.
How can you get atomic mass?
Pick up a periodic table. There are numbers above and below each element. Eg, carbon will have a 6 (atomic number) and 12(.011). The 12.001 is Carbon's mass. If it is molecular mass, it involves adding the atomic masses together. And remember, say if it is O2 you add it twice because there are two of that element.
How do you learn atomic masses and atomic number?
Atomic mass is found on the periodic table as the weighted average of all isotopes of an element. Atomic number is also found on the periodic table and represents the number of protons in an atom's nucleus. You can use the periodic table to easily find both atomic mass and atomic number for each element.
What is an atomic compound?
An atomic compound is a compound that is made up of different elements chemically bonded together in fixed proportions. In contrast to molecular compounds, which are made up of molecules, atomic compounds are composed of individual atoms. Examples include sodium chloride (NaCl) and iron oxide (Fe2O3).
What are the chemical name mono-atomic and polyatomic ions?
Chemical name of (negative) mono-atomic anions ends with -ide, eg. chloride (Cl-), sulfide (S2-), oxide. Chemical name of (negative) poly-atomic anions ends with -ate or -ite for their higher and lower oxidation state respectively, eg sulfate and sulfite. The only one polyatomic ending on -ide is hydroxide OH-. Positive mono-atomic ions are metal ions and they will have the name of the corresponding metallic element, only when two different oxidation states are possible their chemical names will end on -ic or -ous (for high and low oxidation states respectively), eg. ferric (Fe3+) and ferrous (Fe2+) The only positive poly-atomic ion I can think of now is ammonium ion for NH4+.
What is bluish?
something that resembles a blue tone eg to describe a sky to describe a material to describe a bruise etcc
Which refers to atoms with the same atomic number but different atomic masses?
They are called isotopes. eg we have different isotopes of carbon
What verbs describe the word opportunity?
Opportunity is a noun and verbs don't describe nouns.Adjectives describe nouns.good opportunitymissed opportunityrare opportunityVerbs show actions eg walk, run, build, hammeror states eg love, hate, know, like
What are verbs that describe Hades?
Hades is a noun and verbs don't describe nouns, adjectives describe nouns.Verbs are words that show actions eg walk / run / talk or states eg feel / love / hate
What kind of matter is when formed when atoms of two or more elements bond?
If three or more elements are bonded together in a compound (Eg. H2SO4) then that compound is called a "Polyatomic" ion. "Poly" meaning three or more. If there are only two atoms, it is Diatomic (Di meaning two). An example of a diatomic molecule would be CO2.
Why a certain atom exist alone?
it can exist alone as a diatomic molecule eg O2 oxygen
What do you called in an element having the same atomic number but different atomic masses?
Isotopes. eg U235 and U238. Both Uranium, atomic number 92, bur different isotopes.
What information might an adjective give you about a noun?
Adjectives describe nouns, they describe the qualities of people, things, places. They tell about size, colour, age, feelings about the noun (eg beautiful) or they define the noun (eg African).
What type of matter is formed whe two or more elements chemically join together?
If three or more elements are bonded together in a compound (Eg. H2SO4) then that compound is called a "Polyatomic" ion. "Poly" meaning three or more. If there are only two atoms, it is Diatomic (Di meaning two). An example of a diatomic molecule would be CO2.
What are two verbs ending in -ing that describe north in the 1800's?
Verbs don't describe they are actions eg I walk or states I love. Adjective descibe, some adjectives end in -ing. eg interesting Adjectives that describe north: interesting - surprising - debilitating (not sure what you mean by north maybe the north?)
How do you describe a Missile in words For eg awesome food?
Words that describe nouns are adjectives; the word missile is a noun. Some adjectives that can describe a missile are:awesome (awe inspiring)fastsleekswiftfleetspeedyballisticsupersonic
