What is Chemistry? ✔Correct answer-The study of the composition, properties, and
transformations of substances
about how many naturally occurring fundamental substances are there ✔Correct answer-105
naturally occurring fundamental substances are better known as. . . ✔Correct answer-elements
what are the three subatomic particles of matter that make up an atom ✔Correct answer-proton,
neutron, and electrons
what atom is the smallest ✔Correct answer-hydrogen
what makes hydrogen atoms unique from other atoms ✔Correct answer-it has no neutrons in its
nucleus
elements are made up of indivisible particles called ✔Correct answer-atoms
when do chemical changes occur in atoms ✔Correct answer-when combined, separated, or
rearranged
an ice block melts in the sun, is this an example of chemical transformation? ✔Correct answer-no,
because the composition of ice does not change, ice can become water and water become ice
without a molecular change.
what is the difference between elements and compounds ✔Correct answer-elements contain
single atoms, whereas compounds are made up of more than one type of atom
what is the charge of a neutron and where is it located in the atom ✔Correct answer-neutral,
nucleus
what is the charge of a proton and where is it located ✔Correct answer-positive, nucleus
what is the charge of an electron and where is it located ✔Correct answer-negative, in the orbital
rings
what model describes the types of sub-atomic particles contained in an atom ✔Correct answer-
Ernest Rutherford
although each subatomic particle are considered building blocks, alone, they do not. . . ✔Correct
answer-manifest the characteristic of any element
what three atoms are the main types of atoms found in essential oil molecules ✔Correct answer-
carbon, hydrogen, oxygen
,what function do neutrons appear to have in an atoms ✔Correct answer-to prevent protons in the
nucleus from repelling one another
what is the difference between hydrogen, carbon, and oxygen ✔Correct answer-the primary
difference is the number of subatomic particles associated with each. Hydrogen has 1P, 0N, 1E;
carbon has 6P, 6N, 6E: and oxygen has 8P, 8N, 8E.
an element is a substance that ✔Correct answer-cannot be broken down into other substances
matter exist in three phases ✔Correct answer-solid, liquid, gas
a chemical change in a substance results in ✔Correct answer-the formation of a new substance
the atomic number is characterized by ✔Correct answer-the number of protons in the nucleus
T/F: there is the same number of protons as there are electrons ✔Correct answer-true
atomic mass equals ✔Correct answer-the number of protons and the number of neutrons in the
nucleus
atomic number and atomic mass are virtually the same thing ✔Correct answer-true
T/F: Oxygen atoms have six electrons in their outer orbital. ✔Correct answer-true
T/F: Neutrons are small negatively charged particles that orbit the nucleus of any atom. ✔Correct
answer-false, neutrons are neutral and found in the nucleus
T/F: Atoms are found in every living thing. ✔Correct answer-true
T/F: Hydrogen atoms have no neutrons. ✔Correct answer-true
T/F: Compounds are molecules containing several atoms of the same type. ✔Correct answer-false,
compounds are made of two or more different atoms
Choose the correct answer below to complete this sentence correctly: Carbon atoms have a total of
___ electrons. Four of these are located in the outer orbital. Oxygen by contrast, has a total of ___
electrons, _____ of which are in the outer orbital. ✔Correct answer-6,8,6
T/F: Everything that exists is made up of virtuons, which are imaginary particles. ✔Correct answer-
false, WTF are virtuons
T/F: Neutrons will attract electrons ✔Correct answer-false, neutrons will not affect electrons
The gas oxygen is an element. The liquid water is a compound. describe what the difference is
between compounds and elements. ✔Correct answer-Oxygen gas is an element because it
contains only one type of atom Water is a compound because it contains two different types of
atom.
Which subatomic particle has no attractive or repulsive effect on electrons? ✔Correct answer-
neutrons
, Explain why most atoms bond together to form molecules ✔Correct answer-to fill the vacancies
left in their outer orbitals, making themselves more stable
what elements have a full outer shell (orbital) ✔Correct answer-helium and neon
what effect does the full outer shell have on the reactive capabilities of atoms of this element
✔Correct answer-The full outer orbital makes them unreactive because they do not need to react
with other atoms to achieve stability
what is the max number of electrons in the first orbital ✔Correct answer-2
what is the max number of electrons in the second orbital ✔Correct answer-8
what is a double bond? Explain in terms of the number of electrons shared between the atoms
✔Correct answer-a double bond is when they share two pairs of electrons
which atomic symbol alway gets written first in chemical formulae of organic molecules ✔Correct
answer-carbon symbol C
if you were told a molecule had 7 atoms of hydrogen, 3 atoms of carbon, and 1 atom of oxygen, write
a correct chemical formula for it ✔Correct answer-C3H7O
what is an ion ✔Correct answer-atoms that have either gained or lost one or more electrons
ionic bonding occurs when ✔Correct answer-electrons are transferred between ions of opposite
charges so that their outermost orbitals are full
atoms are --- charged ✔Correct answer-neutrally
a --- orbital is more stable energetically than a --- --- orbital ✔Correct answer-full, partially full
helium atoms has how many full orbitals ✔Correct answer-1
what two elements have yet to be discovered in molecules ✔Correct answer-helium and neon
bonding is ✔Correct answer-interaction between two atoms
what are the two types of bonding ✔Correct answer-ionic and covalent
a covalent bond is ✔Correct answer-when two atoms share electrons to fill their orbitals
what is the simplest molecule bond ✔Correct answer-hydrogen
how are atoms usually represented in short hand ✔Correct answer-latin or greek name
according to convention, how are hydrogen, oxygen and carbon listed in the formula ✔Correct
answer-1. carbon, 2, hydrogen, 3. oxygen
in essential oils, what two elements will make double bonds ✔Correct answer-carbon and oxygen
