which statement about electrons is true?

a. electrons have no charge.
b. electrons have a positive charge.
c. electrons have a negative charge.

These are 3 questions and 3 answers.

Question 1.

I = 0.01 A

Explanation:

a) Data:

i) Type of circuit: series

ii) R₁ = 100 Ω

ii) R₂ = 100 Ω

iii) V = 2 V

iv) I = ?

b) Formulas

i) Equivalent resistance, R = R₁ + R₂

ii) Ohm's law, V = IR

c) Solution

i) R = 100Ω + 100Ω = 200Ω

ii) I = V / R = 2 V / 200Ω = 0.01 A

Question 2)

False.

Explanation:

The nuclear model of the atom states that the atom is neutral, and consists of a nucleus, which holds the protons and the neutrons, and the electrons which are around the nucleous (in regions called orbintals).

The electrons are negatively charged and the protons are positively charged.

The magnitudes of the charges of both electrons and protons are equal.

Therefore, for the atom be neutral, the neutrons cannot have charge.

Question 3.

oppose (or resist).

Explanation:

1) The most basic electrical circuit consists of a 1) potential difference (voltage) source, which gives the "impulse" to the charge to flow, 2) the wire, which is the medium through which the charge flows), and 3) a resistor.

The resistor is the element with "resistance" to the flow of charge, this is it resists or oppose the flow of charge.

Some components, like motors, filaments, buzzers, which content or are resistors per se, transform the current (flow of charge) in other useful forms of energy (motion, light, heat, sound).

The resistor meets Ohm's law which states R = V / I, at constant temperature.

The ion has more protons than electrons.

Explanation:

The given statement "protons and neutrons both have positive charge, and electrons have negative charge" is false.

Option 2

Explanation:

The atoms of all elements are made up of tiny particles that were unknown to the world for many years. With the efforts of wise brains such as J.J. Thomson, Rutherford and Chadwick, it has been concluded that an atom is not the smallest particle and is comprised of three tiny particles’ combination- Protons, Electrons and Neutrons.

The protons have a natural positive charge that attracts the equal but opposite charge towards them and they are electrons. Electrons have a negative charge and revolve around the nucleus of an atom in their constituent orbits.

Neutrons don’t have any charge on them and hence, remain at rest inside the nucleus of atoms. They are actually the flipped iso-spins of protons. The purpose of neutrons in the nucleus is to create a balance between two or more protons so that they can co-exist in the nucleus and it may not scatter.

False

Explanation:

Protons are positively charged, electrons are negatively charged, and neutrons have no charge.

D

Explanation:

The number of electrons are equal to the number of neurons but differ in mass and size

C

Explanation:

Atoms are basically the building blocks of matter and consist of protons,neutrons and electrons which are all subatomic particles(occupy within an atom).They include:

Protons; which arr subatomic particles with a positive charge of +1.Neutrons: which (as the name implies)are neutral and have no electrical charge.Electrons: which have a negative charge of -1.

Hope this helps!

B) Within an atom, an electron can have only particular energies.

Explanation:

As we know that electrons have energy but apart from electrons we know that protons and neutrons inside the nucleus of atom will also have energy in them.

rest all the statements are true as we have

A) Electrons orbit the nucleus rather like planets orbiting the Sun.

TRUE, because electrons can move in stationary orbit around the nucleus

C) Electrons can jump between energy levels in an atom only if they receive or give up an amount of energy equal to the difference in energy between the energy levels.

Difference amount of energy is lost or absorbed by the electron in form of photons

D) An electron has a negative electrical charge.

Charge of an electron is given as

E) Electrons have very little mass compared to protons or neutrons

Mass of an electron is given as

mass of proton or neutron

Answer electrons are negative. Protons are positive, and neutrons are neutral

A

Explanation:

Electrons do not orbit the nucleus rather like the planets orbiting the Sun. Electrons do not orbit they are simply used for a microscope, laser, radiation therapy, and electronics.

it is c as protons have a positive charge

Explanation:

protons =positive
