A lithium is an element, which is an atom. An atom comprises of a nucleus which contains the protons and neutrons. The electrons are negatively charged atomic particles that orbit around the nucleus. The atom in a whole is neutral because the protons and electron number is always even.
nucleus... if it is still "lithium". Otherwise, it is 3 protons and some neutrons, depending on the isotope of lithium.
Protons and Neutrons
3 protons and 4 neutrons
an isotope of the element helium is obtained.
A lithium atom contains three protons, three electrons, and usually four neutrons in its nucleus. The electrons occupy energy levels around the nucleus in a specific configuration.
The atomic weight of lithium (6.941 amu) measures the average mass of an atom of lithium compared to 1/12 of the mass of a carbon-12 atom. It represents the sum of protons and neutrons in the nucleus of a lithium atom.
A lithium atom with 2 electrons would still be considered a lithium atom because the number of protons in the nucleus determines the element. However, it would be considered a lithium ion with a 2+ charge due to the loss of 1 electron.
Yes, the number of protons in an atom and its ion of lithium is the same. Lithium always has 3 protons in its nucleus, regardless of whether it is in its neutral atom form (Li) or as an ion with a different number of electrons.
The lithium atom has no charge because it has an equal number of protons and electrons. Protons are positively charged particles found in the nucleus of an atom, and electrons are negatively charged particles orbiting around the nucleus. In a neutral atom, the positive charge of the protons cancels out the negative charge of the electrons.
Lithium typically has 3 or 4 neutrons because lithium has an atomic number of 3, meaning it has 3 protons in its nucleus. Neutrons help stabilize the nucleus of an atom, and having 3 or 4 neutrons allows lithium to have a stable configuration.
