Which of the following statements is true for isotopes?

Which of the following are true statements regarding isotopes? Isotopes have the same number of neutrons but a different number of protons. Isotopes are different individual chemical elements. Isotopes have the same number of protons but a different number of neutrons.

Which of the following is true of an isotope quizlet?

Which of the following is true of an isotope? Isotopes have the same number of protons, but differ in the number of neutrons they contain. … Using mass numbers notation, we can identify the number of protons, electrons, and neutrons.

Which of the following is the correct definition of an isotope?

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. Every chemical element has one or more isotopes.

Is an isotope of an atom with a larger number of neutrons is larger than an isotope of the same atom that contains fewer neutrons?

Isotopes of the same element differ only in the number of electrons they contain. (b. An isotope of an atom with a larger number of neutrons has a higher mass than an isotope of the same atom that contains fewer neutrons. … All elements have 3 or more naturally occurring isotopes.

Which statement about subatomic particles is true?

The true statement about subatomic particles is A) A neutral atom contains the same number of protons and electrons.

Which of the following is true for an atom?

Atoms are always neutral in nature. … Atoms consist of three basic particles, protons, electrons, and neutrons. The nucleus (center) of an atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and they contain the electrons.

Which of the following statements is true about the two isotopes of carbon C613 and C612?

Which of the following statements is true about the two isotopes of carbon C613 and C612? They have different numbers of neutrons.

Is an isotope with more neutrons larger?

An isotope of an atom with a larger number of neutrons is larger than an isotope of the same atom that contains fewer neutrons.

What is true about radioactive isotopes of an atom?

Different isotopes of the same element have the same number of protons in their atomic nuclei but differing numbers of neutrons. Radioisotopes are radioactive isotopes of an element. They can also be defined as atoms that contain an unstable combination of neutrons and protons, or excess energy in their nucleus.

Which of the following is true about carbon-12 and carbon-14?

Carbon-12 and carbon-14 are two isotopes of the element carbon. The difference between carbon-12 and carbon-14 is the number of neutrons in each of their atoms. … Atoms of both isotopes of carbon contain 6 protons. Atoms of carbon-12 have 6 neutrons, while atoms of carbon-14 contain 8 neutrons.

Which of the following statements explains how two isotopes of the same element are different?

Isotopes of an element refer to atoms that contain the same number of protons in the nucleus but a different number of neutrons. Since the number of neutrons differs the mass of each isotope of an element differs slightly.

What are the two isotopes of carbon?

Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons.

Why is carbon-12 considered an isotope?

Isotopes are forms of the same element with equal numbers of protons but different numbers of neutrons. For example, both carbon-12 and carbon-14 have 6 protons. But carbon-12 has 6 neutrons while carbon-14 has 8 neutrons. By definition, carbon-12, carbon-13 and carbon-14 are all isotopes of the carbon.

When considering the isotopes of carbon-12 carbon-13 and carbon-14 What is it that makes all these carbon?

Carbon 12, 13 and 14 are carbon isotopes, meaning that they have additional neutrons: Carbon 12 has exactly 6 protons and 6 neutrons ( hence the 12 ) Carbon 13 has 6 protons and 7 neutrons. Carbon 14 has 6 protons and 8 neutrons.

Why is carbon-14 not an isotope?

“Carbon-14, perhaps the most important isotope to life on Earth, was ‘born’.” Carbon-14 has six protons and eight neutrons in its nucleus. … Crucially, those two extra neutrons make the nucleus of a carbon-14 atom unstable so that it decays radioactively into an atom of nitrogen.

How do you determine isotopes?

Look up at the atom on the periodic table of elements and find out what its atomic mass is. Subtract the number of protons from the atomic mass. This is the number of neutrons that the regular version of the atom has. If the number of neutrons in the given atom is different, than it is an isotope.

Which of the following elements are isotopes?

For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively. The atomic number of carbon is 6, which means that every carbon atom has 6 protons so that the neutron numbers of these isotopes are 6, 7, and 8 respectively.

What does an isotope look like?

How do isotopes compare and contrast?

Isotopes are atoms that have the same numbers of protons but different numbers of neutrons. An ion is an atom that has gained or lost electrons, so it now has more or fewer electrons than it does protons. So an ion has a negative or positive charge.

How do you determine the most common isotope?

The most common isotope can be found by rounding the atomic weight found on the periodic table of elements to the nearest whole number.

How are isotopes formed?

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 reactor.

Are isotopes positive or negative?

Only about 118 different elements are known to exist. An atom is the smallest part of an element that can exist either alone or in combination with other atoms. Isotopes are atoms that have the same number of protons but different numbers of neutrons. An ion is an atom or molecule with a positive or negative charge.

Why do all isotopes have the same properties?

Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.
