if a lithium nucleus contains 3 protons and 4 neutrons. What is its atomic mass?
Odilia Olvera
Lithium by default contains 3 protons and 4 neutrons so its Atomic Mass is 6.941 amu (atomic mass units)

∙ 14y agoTo calculate the mass of Lithium's nucleus, one would use the formula:
nuclear mass = A x u
Where A is the number of protons and neutrons and u is the value one an atomic mass unit (1.66x10^-27 kg)
So:
7x1u = 1.162x10^-26 kg

How many protons are in a lithium nucleus?
The atomic number of lithium is 3. Therefor there are 3 protons and neutron in the nucleus of lithium. Lithium also has 4 neutrons. atomic # = protons and neutrons neutrons = rounded atomic mass - atomic number Sources- 7th grade Acc. Science
The nucleus of an atom contains the?
It contains the nucleons (protons and neutrons)
The central part of an atom that contains protons and neutrons?
nucleus
Does the nucleus contain neutrons and electrons?
No, the nucleus contains protons and neutrons. Electrons are outside of the nucleus.
What is contained inside the nucleus of an atom?
The nucleus of an atom contains sub atomic particles such as protons which are positively charged and neutrons which do not have a charge. Protons and neutrons are collectively termed as nucleons.
