How can atoms make up all of the substances around you quizlet?
Compare the charges and masses of protons, neutrons, and electrons. How can atoms make up all of the substances around you? Different types of atoms and different numbers of atoms join together in different combinations to form all of the different substances.
How do atoms make up everything?
Everything in the universe (except energy) is made of matter, and, so, everything in the universe is made of atoms. An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. The electrons carry a negative charge and the protons carry a positive charge.
What substances are made up of atoms?

||A pure substance that is made entirely from one atom Eg:
||Are pure substances made up entirely from two or more elements that are chemically combined
|Law of Conservation of Energy
||Mass cannot be created nor destroyed in ordinary chemical of physical changes
How do atoms create life?
Atoms don’t assemble into life forms. Molecules, made of atoms, did assemble into life and they still do so today. Life is an ongoing chemical chain reaction of molecules. The question of “why” can be answered by : Because molecules can!
How do we use atoms in everyday life?
multitide of uses (drinking, cleaning, cooking, transportation). Without water we would not survive. -Lead atoms bond together and they make up the lead that we use as a pencil. -Copper atoms, aluminum atoms, nickel atoms, etc., all make up metal which is used for a variety of things in everyday life.
How do you explain an atom to a child?
The atom is the basic building block for all matter in the universe. Atoms are extremely small and are made up of a few even smaller particles. The basic particles that make up an atom are electrons, protons, and neutrons. Atoms fit together with other atoms to make up matter.
What would happen if there were no atoms?
Atoms make up everything around you – everything you see, hear, touch smell and taste. Without atoms, the chemical elements couldn’t exist – without chemical elements, then molecules wouldn’t exist, then proteins wouldn’t exist, then life wouldn’t exist! If you removed two atoms, you could still live.
Why is an atom neutral?
Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
How do you know if an atom is neutral?
A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral.
What must be true if an atom is ionized?
A stable atom has a net charge of 0. In other words, it has an equal number of protons and electrons. The positive protons cancel out the negative electrons. When the number of electrons does not equal the number of protons, the atom is ionized.
What is it called when an atom is charged?
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION.
What is the charge on all atoms?
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral.
How do you know the charge of an isotope?
If protons outnumber electrons, the isotope has more positive charges than negative charges. In other words, the number of protons exceeds the number of electron by the same number as the positive charge. If the number of electrons exceeds the number of protons, the ion charge will be negative.
How do you determine the most common isotope?
To determine the most abundant isotopic form of an element, compare given isotopes to the weighted average on the periodic table. For example, the three hydrogen isotopes (shown above) are H-1, H-2, and H-3. The atomic mass or weighted average of hydrogen is around 1.008 amu ( look again to the periodic table).
Do all elements have isotopes?
All elements have isotopes. There are two main types of isotopes: stable and unstable (radioactive). There are 254 known stable isotopes. All artificial (lab-made) isotopes are unstable and therefore radioactive; scientists call them radioisotopes.
What causes isotopes to form?
Isotopes can either form spontaneously (naturally) through radioactive decay of a nucleus (i.e., emission of energy in the form of alpha particles, beta particles, neutrons, and photons) or artificially by bombarding a stable nucleus with charged particles via accelerators or neutrons in a nuclear reactors.
What are isotopes in simple words?
Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties.
How do isotopes work?
An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
What are isotopes answer?
Isotopes are versions of the same element. They have the same number of protons and electrons as the element but different mass numbers and number of neutrons.
Which of the following is an example of isotope?
Isotope Notation For example, an isotope with 6 protons and 6 neutrons is carbon-12 or C-12. An isotope with 6 protons and 7 neutrons is carbon-13 or C-16. Note the mass number of two isotopes may be the same, even though they are different elements. For example, you could have carbon-14 and nitrogen-14.
Do Isotopes have the same atomic mass?
Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
