Is this statement true or false The isotope hydrogen-1 is the standard used for the relative scale of atomic masses?
True. Hydrogen-1, also known as protium, is the standard used for the relative scale of atomic masses. Its mass is defined as exactly 1 atomic mass unit (amu) on the atomic mass scale.
True or false the mass of a proton is about one atomic mass unit?
True. The mass of a proton is approximately one atomic mass unit (amu), which is roughly equal to the mass of a neutron.
Is this true or false the mass of a proton is about one atomic mass unit?
True. The mass of a proton is approximately one atomic mass unit (amu). This makes it easier to remember that one proton is roughly the same mass as one amu.
The weight of subtomic particles is measured in units called atomic mass units true or false?
True. Subatomic particles, such as protons, neutrons, and electrons, are measured in units called atomic mass units (amu).
True or false Tritium is an isotope of hydrogen with 2 neutron?
False. Tritium is an isotope of hydrogen with 2 neutrons.
Is this statement true or false The isotope hydrogen-1 is the standard used for the relative scale of atomic masses?
True. Hydrogen-1, also known as protium, is the standard used for the relative scale of atomic masses. Its mass is defined as exactly 1 atomic mass unit (amu) on the atomic mass scale.
Base weight a system of comparing atomic weights to carbon is it true or false?
True. The term "base weight" is used in comparing atomic weights where the atomic weight of carbon-12 is set as the reference standard with a value of exactly 12 atomic mass units. Other elements are compared relative to this standard to determine their atomic weight.
True or false the mass of a proton is about one atomic mass unit?
True. The mass of a proton is approximately one atomic mass unit (amu), which is roughly equal to the mass of a neutron.
True or false that hydrogen is the least common element in the universe?
False. Hydrogen is the most abundant element in the universe, constituting about 75% of its elemental mass.
The number of neutrons is equal to the atomic number true or false?
False as a generalization but true for some isotopes. The atomic number is the number of protons in a nucleus, which may coincidentally be the same as the number of neutrons but is not required to be.
Is the sun made mostly of hydrogen and helium true or false?
True. The Sun is mainly composed of hydrogen (about 74% of its mass) and helium (about 24% of its mass). The remaining 2% consists of trace amounts of heavier elements.
Is this true or false the mass of a proton is about one atomic mass unit?
True. The mass of a proton is approximately one atomic mass unit (amu). This makes it easier to remember that one proton is roughly the same mass as one amu.
The weight of subtomic particles is measured in units called atomic mass units true or false?
True. Subatomic particles, such as protons, neutrons, and electrons, are measured in units called atomic mass units (amu).
State true or false Hydrogen is insoluble in water?
False False False FalseFalse
Is it true or is it false Electronegativity increases continuously as atomic number increases?
False. Electronegativity does not increase continuously as atomic number increases. While there is a general trend of increasing electronegativity across a period from left to right on the periodic table, there are exceptions due to factors such as electron configuration and atomic structure.
Water H2O is composed of hydrogen and oxygen true or false?
True
True or false relative atomic masses sre measured in amus?
true
