What does NET mean in physics?
the overall force acting on an object
Which one will get more electrons when two objects are rubbed together?
The object with a higher electron affinity will tend to gain more electrons when rubbed together with another object. This is because it has a greater ability to attract and hold onto electrons from the other object, resulting in a net transfer of electrons from one object to the other.
What does net force mean in physics?
In physics, net force refers to the overall force acting on an object when all individual forces are combined. It is the vector sum of all forces acting on an object and determines the object's acceleration according to Newton's second law of motion, F = ma.
Is an object's net charge positive or negative if it loses electrons?
An object's net charge becomes positive if it loses electrons because it has an excess of positive protons relative to negative electrons.
A physics teacher rubs a glass object and a felt cloth together and the glass becomes positively charged. Which of the following statements are true?
The glass gains electrons from the felt cloth, becoming negatively charged. Since the glass becomes positively charged, it loses electrons to the felt cloth. The transfer of electrons causes the glass to have a net positive charge. The friction between the glass and felt cloth leads to the exchange of charge, resulting in a net positive charge on the glass.
How many electrons are lost or gained in a chemical reaction?
There is zero NET loss or gain of electrons
Every chemical reaction invloves a net gain or loss of?
electrons
Why some atoms gain or lose electrons to form ions.?
if an atom gains or loses electrons, it is no longer has an equal number of electrons and protons. Because the charges do not cancel completely, the atom has a net electric charge.
What is the net charge of copper atom if it gain two electrons?
Cu(2-) does not exist, because Cu does not gain electrons at all being a metal. When it gives off two electrons Cu(2+) ions are formed.
The type of ion that forms when atoms gain electrons?
Atoms that gain electrons are called anions, and atoms that loose electrons are called cations
What electric charge is the characteristic for an ion of 0?
O that is oxygen is a non metal and a non metal has a characteristic of gaining electrons so when they gain electrons the also gain a net charge in negative as no. of protons become less than the no. of electrons. now oxygen has atomic no. 8 and valency of 2 so it requires 2 electrons to complete an octet i.e. 8 electrons in the outermost shell and to get a negative charge. since it will gain 2 electrons so it will have a net charge -2. The oxidation number of oxygen is -2, except in a few cases, including superoxides (-1/2), peroxides (-1), and oxygen fluorides (+1, +2).
How does sulfide ion obtain its charge?
The sulfide ion (S²⁻) obtains its charge by gaining two electrons. Sulfur, which has six valence electrons, tends to gain two additional electrons to achieve a stable electron configuration similar to that of the noble gas argon. This gain of electrons results in a net negative charge of -2, leading to the formation of the sulfide ion.
What does NET mean in physics?
the overall force acting on an object
What is a total force in physics?
net force
What is the net charge ions in Sodium?
A crystal of salt consists of electrons and positive ions. How does the net charge of the electrons compare with the net charge of the ions
How do atoms gain a charge?
An atom willreceive a charge when it becomes ionized. If the atom looses one of its electrons (-), then there are more protons (+) and it becomes a+1 charge (positive). If the atom gains an electron, then there are more electrons and it becomes a -1 (negative) charge. It depends on the electrons in the valence level (outer level) to decide if it will gain or lose electrons.
What is the net gain of ATP at the end of glycolysis?
The net gain of ATP at the end of glycolysis is 2 molecules of ATP.
