The spheres surrounding the nucleus of an atom are called protons and neutrons, protons hold the electrons in orbit around the nucleus because a proton has a positive charge which attracts the electron which has a negative charge causing electromagnetic force which holds the electron in orbit. The neutron determines the isotope of the atom but has a neutral charge.

What do the orange and yellow spheres represent in a model of an atomic nucleus?

The orange spheres represent protons, which have a positive charge, and the yellow spheres represent neutrons, which have no charge. Protons and neutrons make up the majority of the mass of an atomic nucleus.


What is inside a Galileo thermometer?

A Galileo thermometer contains a clear liquid, usually alcohol or water, and several glass spheres filled with different colored liquids. The spheres are calibrated with specific densities so they rise or fall based on the temperature of the surrounding environment.


What happens when you try to draw an atom?

It is difficult to draw atoms realistically, other than as featureless spheres, which is then not a very informative illustration. The orbit of an electron is not the same as the orbit of a planet, they are not little balls circling around a larger ball in the center. Electrons form shells, they spread themselves out into hollow spheres. They have no fixed shape, but they respond to the electromagnetic forces that act upon them. It is more accurate to say that electrons surround a nucleus, than to say that they orbit a nucleus. But when we draw pictures, we usually draw atoms as if they were miniature solar systems, with little round electrons orbiting the nucleus. And that is not very accurate.


Which of the earth's spheres contains its landforms?

lithosphere


Where inside the electron cloud would you find an electron?

the electrons just bounce around the electron clouds freely. think about 2 spheres, a small one suspended inside a bigger one. the smaller one is the nucleus, and the big one is the cloud. the electrons just bounce around in the space between the nucleus and the cloud


The bohr model is used to illustrate the arrangement of?

The Bohr model is used to illustrate the arrangement of electrons in an atom, showing them in discrete energy levels around the nucleus based on their quantized energy values.


How is the tornadoes produced by these spheres?

Tornadoes produced by spheres are created due to the spinning motion of the spheres causing a swirling effect in the air. As the spheres move, they create a low-pressure area that can draw in surrounding air and create a vortex. This vortex can then intensify into a tornado under the right conditions.


What kind of cell has no nucleus but has a cell wall and shapes like spheres rods and spirals?

What shows the development of atomic models in chronological order?

The development of atomic models in chronological order is as follows: Atoms are solid spheres. Atoms have electrons attached to their surface. Electrons move around nucleus at specific energy levels. Rapid motion of electrons around nucleus in a cloud.


What is earth composed of 4 spheres?

Earth is composed of four main spheres: the lithosphere (solid outer layer), hydrosphere (all water on Earth), atmosphere (layer of gases surrounding Earth), and biosphere (all living organisms on Earth). These interconnected spheres work together to support life on our planet.


Examples of charge by induction?

An example of an induction charging of two metal spheres. The metal spheres are supported by insulating stands so that any charge acquired by the spheres cannot travel to the ground. The spheres are placed side by side (see diagram i. below) so as to form a two-sphere system. Being made of metal (a conductor), electrons are free to move between the spheres - from sphere A to sphere B and vice versa.


How do the Bohr model and the quantum mechanical model of the atom differ in how they describe electrons?

the bohr model suggests that electrons follow orbits around the nucleus. Quantum mechanics describes electrons differently and gives them different properties. It tells us where an electron is most likely to be found but no defined path of motion around the nucleus
