What does the number next to isotopes signify?
The number next to the isotope is the mass number- They all have different masses because they have different numbers of neutrons, but the same amount of protons (Remember protons + nuetrons = mass)
How many protons does zirconium have?
AnswerThere are 40 protons in the element "zirconium". There are a number of isotopes of Zr, with the most common having an atomic weight (protons plus neutrons) of 90, with 94 and 92 tied for second place. That leaves 50 neutrons as most common, with 52 or 54 neutrons as alternatives.
Number of protons and electrons in lithium?
Lithium has three protons and three electrons. The number of electrons always equals the number of protons. Lithium has two isotopes, one with three neutrons and one with four neutrons.
An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
In an atom the number of proton equals the number of neutrons?
In an atom, the number of protons is equal to the number of electrons in order to maintain electrical neutrality. However, the number of neutrons in an atom can vary, leading to different isotopes of the element.
WHAT Equals the sum of the number of neutrons and protons in an isotope?
The atomic mass equals neutrons and protons. This is true in non isotopes as well.
How do the numbers of protons neutrons and electrons for an element compare?
In the neutral state, all atoms of the same element contain equal numbers of protons and electrons. However, most elements have atoms with different numbers of neutrons. These are called isotopes.
How much newtrons are in iron?
How many neutrons, not how much newtrons. Iron's atomic number is 26, so it has 26 protons; its atomic mass is approximately 56, which equals the number of protons and neutrons. 56 - 26 = 20 neutrons. While there are isotopes of iron with more or fewer neutrons, this is likely the answer you're expected to provide. If not, see Wikipedia "isotopes of iron".
How many protons newtrons and electrons?
An atom's nucleus contains protons and neutrons, while electrons orbit around the nucleus. The number of protons defines the element, the number of neutrons can vary within isotopes of the element, and the number of electrons equals the number of protons in a neutral atom.
Is the number of protons equal to the number of neutrons in an atom?
The number of neutrons in an atom CAN be equal to the number of protons and electrons, BUT IT IS NOT ALWAYS. You can find the number of neutrons in an atom by subtracting the atomic number from the mass number. The number is often the same among the lighter elements, but the ratio of neutrons to protons quickly grows larger than one (on average) as you go further along the periodic table.
What does the number next to isotopes signify?
The number next to the isotope is the mass number- They all have different masses because they have different numbers of neutrons, but the same amount of protons (Remember protons + nuetrons = mass)
True or false The number of neutrons always equals the number of protons?
False. The number of electrons always equals the number of protons for an element and this is called the atomic number of an element. The number of neutrons in an element depends on other factors and varies by element and the same element can have different versions with a different number of neutrons. Each version is called an isotopes. The sum of the protons and neutrons in an atom is called the atomic weight. Hydrogen has three isotopes with 0, 1, or 2 neutrons, with atomic weights 1,2, 3). Isotopes with 1 or 2 neutrons are extremely rare. Carbon has four isotopes. It can have 5, 6, 7, or 8 neutrons (atomic weights 11, 12, 13, 14). We commonly refer to different isotopes by its name and weight as in carbon-11, carbon-12, carbon-13, carbon-14. Carbon-12 is common and everywhere. the others are very rare. Carbon-11 and carbon-14 are considered unstable and tend to brake down into other elements over a period of time releasing energy as it happens. This is called radioactivity.
Is the atomic number of an atom equal to the number of protons or neutrons or electrons in the nucleus?
The atomic number of an atom is equal to the number of protons in the nucleus. It determines the element's identity and position on the periodic table. Electrons and neutrons can vary in number to form different isotopes of the element.
