Explanation:
An atom is made up of:
- Protons which are the positively charged particles
- Electrons are negatively charged
- Neutrons carry no charges.
Atomic number is the number of protons in an atom.
To find the nuclear charge:
We use the effective nuclear charge formula:
Effective nuclear charge = Atomic number - number of shielding electrons(non-valence electrons)
The shielding electrons are the non-valence electrons in the inner orbitals.
For example:
Ne:
atomic number = 10
Effective nuclear charge = 10 - (2) = 8+
Number of non-valence electrons is 2
The effective nuclear charge is 8+
Overall charge:
Charge = number of protons - number of electrons
For neutral atoms, the overall charge is zero as the number of protons and electrons are the same.

Answer:
This question is incomplete
Explanation:
This question is incomplete but one can assume the answer from the definition of quantum mechanics. Quantum mechanics is the science that describes particles in nature at the atomic and subatomic particle (electron, proton and neutron) level. Thus it can be assumed that atoms and subatomic particles are used to broadly describe particles.
Election current because voltage is a measurement, information doesn't apply to all electrical devices and the wires within are usually copper bc it conducts and hardly ever will the wires be anything different because copper is cheap
Magnesium potassium phosphate hexahydrate and a number of its deuterated counterparts were studied for their Fourier transform infrared and Raman spectra. By contrasting the spectra obtained at the boiling point of liquid nitrogen with those obtained at ambient temperature and by examining the spectra of a succession of partially deuterated MgKPO4
<h3>What is Infrared and raman spectroscopy ?</h3>
Raman and infrared spectroscopy both investigate how radiation interacts with molecular vibrations, but they do so in different ways depending on how the photon energy is delivered to the molecule by altering its vibrational state.
- While IR spectroscopy depends on a change in the dipole moment, Raman spectroscopy depends on a change in the polarizability of a molecule. In contrast to IR spectroscopy, which measures the absolute frequencies at which a sample absorbs light, Raman spectroscopy measures the relative frequencies at which a sample scatters light.

I would get a container and weigh it. Then I would put the bouncy balls in the container and weigh it again. Then I would Subtract the weight of the container without the bouncy balls from the container with the bouncy balls.
