How many electrons pass through a conductor in 1 min and 30s if the current is 4mA?
To calculate the number of electrons passing through a conductor, we first convert the current to coulombs per second (C/s) by multiplying 4mA by 10^-3 to get 0.004A. Then multiply this by the total seconds in 1 min and 30s (90s) to get 0.36 coulombs. Since 1 electron has a charge of 1.6 x 10^-19 coulombs, divide the total charge by the charge of one electron to find the number of electrons passing through the conductor (0.36 / 1.6 x 10^-19 ≈ 2.25 x 10^18 electrons).
How calculate electrons?
To calculate the number of electrons, you need to know the total charge of the system or material in question and the charge of a single electron (approx. -1.6 x 10^-19 coulombs). By dividing the total charge by the charge of a single electron, you can determine the number of electrons. Formula: Total number of electrons = Total charge / Charge of a single electron.
What is the total charge of electrons in a sodium ion?
A sodium atom has 11 electrons so the total charge of all the electrons in a sodium ion is -10.
What is the property of an atom found by adding the total charge of protons to the total charge of electrons?
The property of an atom found by adding the total charge of protons to the total charge of electrons is the net charge of the atom. If the total charge of protons equals the total charge of electrons, the atom is neutral. If there is a difference between the two, the atom becomes either positively or negatively charged.
What is its total charge of 17 protons and 10 electrons?
The total charge would be +17 + (-10) = +7.
How many unpaired electrons does phosphorus with the charge of negative three have?
18. Phosphorus posses 15 electrons and 15 protons, respectively its charge is 0.By accepting 3 more electrons, with their negative charge the total charge of the atom would decrease by 3.So the total charge would be -3 and the total number of electrons would be 18.
What is the total electric charge of 1.7 kg of electrons?
The total electric charge of 1.7 kg of electrons is approximately -2.7 x 1028 Coulombs.
What is the total charge if you have 14 protons 14 neutrons and 12 electrons?
If the atom is stable and neutral, it will have 14 electrons. If it has a positive charge it will have less electrons, and if it has a negative charge it will have more electrons.
What charge does 2 electrons have?
2 unbalanced electrons have a 2- charge on the molecule/atom
How many electrons are PHOSPHATE -3 ION?
The phosphate ion is a polyatomic ion with a total charge of -3. This means it has gained 3 electrons to achieve an overall negative charge, so it has a total of 30 electrons.
What is the charge of a particle with 36 electrons 49 neutrons and 38 protons?
To determine the charge of the particle, we need to consider the charges of the electrons and protons. Electrons have a charge of -1 each, while protons have a charge of +1 each. With 36 electrons, the total negative charge is -36, and with 38 protons, the total positive charge is +38. Therefore, the overall charge of the particle is +38 - 36 = +2, indicating that the particle has a charge of +2.
Are metals and non metals electrically neutral?
Yes. Atoms have protons (positive charges) and electrons (negative charges). However, quite often it is the negative charges (the electrons) that carry the current. In any case, the net charge in a conductor is usually zero (it is neutral) - the electrons simply go in one end and out the other, but the total number of electrons will doesn't change in normal circumstances, whether there is a current or not.
