What is a stream of particles containing two neutrons and two protons?
A stream of particles containing two neutrons and two protons is an alpha particle. Alpha particles are emitted during alpha decay in radioactive processes. They have a positive charge and are relatively heavy compared to other types of particles.
What is rearrangement of electrons on an uncharged object without direct contact with a charged object?
The rearrangement of electrons on an uncharged object without direct contact with a charged object is known as electrostatic induction. This occurs when a charged object is brought near the uncharged object, causing the electrons in the uncharged object to redistribute and create regions of positive and negative charge without physical contact.
Is modulus of difference between two positive integers positive?
The modulus would be described as the distance between, it is without direction and would therefore always be positive.
What charge does subatomic particle of atom have?
Protons: positive charge Electrons: negative charge Neutrons: without electrical charge
In the bohr model of the atom which characteristics of electrons is limited?
In the Bohr model, electrons are limited in their energy levels or orbits around the nucleus. Electrons can only exist in specific quantized energy levels, and they are restricted to move in circular orbits without emitting radiation.
Why do mobile phones need radiation to work?
because without radiation it wouldn't have access to web without it
How do you know if an ion has a negative or positive charge?
If you want to find out whether an atom contains positive ions or negative ions, you will generally need to look it up. However, there are some general rules that can help you figure it out without research. First of all, there are 3 types of elements on the periodic table: metals, nonmetals, and metalloids. The majority of elements are metallic. Atoms tend to form ions based on whether they gain or give away electrons (e-) when bonding with other elements. Nonmetals tend to form anions (negative ions), meaning that they gain 1 or more electrons when forming a bond. Metals, on the other hand, tend to lose electrons when bonding, so they are most likely to form cations (positive ions).
Electrons can move through objects.?
yes they can move through inanimate objects.
What is alpha radiation made of?
Beta particles are made of either electrons (or their opposite particle - positrons). They are emitted from certain atomic nuclei in the process of radioactive decay. Electrons and positrons are considered one of a class of subatomic particles called "Elementary Particles". Elementary particles are believed to have no further substructure, and are therefore made only of energy by the formula E= mc^2.
What is the total charge on plasma?
Usually, the total charge of plasma is neutral. Of course, there are exceptions. As the atoms are energized, electrons are released into the system. That release leaves a bunch of positive and negative charges.
How do you permanently charge an electroscope without bringing it into contact with a charged rod?
You can permanently charge an electroscope by induction. Place a positively charged rod close to the electroscope without touching it. The electrons in the electroscope will be repelled to the top leaving a positive charge at the bottom. Remove the charged rod, then ground the top of the electroscope. This will transfer the excess electrons to the ground and leave the positive charge at the bottom, effectively permanently charging the electroscope.
Why isoelectronic ion with higher positive charge has smaller size?
The traditional explanation for this is that the electrostatic attraction of the electrons to the nucleus of an atom is reduced by repulsion of the other electrons present in an atom without positive charge. If an isoelectronic ion has a positive charge, the effect of repulsions is reduced because of the smaller number of electrons, and the resulting stronger attraction to the positively charged nucleus pulls the outer electrons closer. However, all such questions about the properties of atoms should preferably be answered in a purely mathematical manner by quantum mechanics.
