What else can I help you with?
Have about 1800 times less mass than protons and neutrons?
Electrons have ~1800 times less mass than protons and neutrons
What is an element with more or less neutrons than average?
isotope
Why can an element have the same atomic mass as another element?
Two elements can have the same atomic mass if one has more or less neutrons than protons in the nucleus. These are called isotopes. not much to im prov thank you
Is a noble gas with 48 neutrons and a mass of less than a 100?
The noble gas with 48 neutrons and a mass of less than 100 is Krypton. It has an atomic number of 36, which means it has 36 protons in its nucleus. The total mass of Krypton is slightly less than 100 atomic mass units.
Which element has 10 neutrons is a nonmetal and has an atomis mass greater than 19?
Neon
Why can't the mass number be smaller than the atomic number?
The mass number has to be greater then the atomic number because the mass number is the protons plus the neutrons. If you were to take 10-12 you would get a negative number of 2 and there can't be a negative number of neutrons!
Is it true that the mass number of an atom can be less than the proton?
No, the mass number of an atom is always equal to or greater than the number of protons in its nucleus. The mass number is the sum of the protons and neutrons in an atom. If an atom had fewer protons than its mass number, it would be a different element altogether.
What is an aton with a different mass number than normal?
An isotope of the element. The mass number is the number of protons and neutrons in the nucleus.
What element has an atomic mass greater than 75 but less than 79?
Element 34, Selenium, has an atomic mass of about 78.96.
How many protons does and atom with and atomic number of 23 and a mass number of 51 have?
23 Protons and 28 Neutrons. The atomic number is always equal to the number of protons in an element. The element is vanadium (symbol V). Any atom with 23 protons is be vanadium, but some vanadium atoms will have more or less than 28 neutrons. The mass number is the sum of the number of protons and neutrons together, and this can vary for the same element (called isotopes). To find the number of neutrons, just subract the atomic number from the mass number.
Why atomic mass is always greater than atomic number?
Atomic mass includes the total mass of protons, neutrons, and electrons in an atom. Since protons and neutrons contribute significantly to the mass of an atom, atomic mass is generally greater than atomic number, which represents the number of protons in the nucleus. Electrons have a much smaller mass compared to protons and neutrons, so they have less impact on the overall atomic mass.
Why don't we use the mass of the electron to get the atomic mass of an element?
The number of electrons are variable for an element because electrons can be lost or gained. Additionally, the mass of an electron is so much smaller than the mass of neutrons and protons that it can be considered negligible for most purposes.
