This is called an ion.
the charge on an Ion is - if electrons have been added :)
'-3' It is not an atom, when it is a charged species, but an ION. 15 protons (15+) 18 electrons (18-) Hence +15 - 18 = -3 The charge. By the numbers given , this is the element Phosphorus. , which can exhibit a 'P^(-3) ion.
Electrons have a negative charge. Protons have a positive charge, and neutrons have a neutral charge. Added: Electrons always have a negative charge, value: minus 1.602*10-19 Coulomb.
When you make an object charged, you have either added or removed electrons from it. Adding electrons makes it negatively charged, and removing electrons makes it positively charged. Electrons move onto the object, giving it a static charge.
The number of protons determines the number of electrons in the ground state of the atom. However electrons can be subtracted or added when the atom is not in its ground state, creating ions.
Yes, all vectors can be added or subtracted.
Electrons are the particles that move when an object acquires a net positive or negative charge. In the case of a positive charge, electrons are removed from the object, leaving an excess of positive charge. Conversely, in the case of a negative charge, electrons are added to the object, creating an excess of negative charge.
The numerator is whats being subtracted or added when you are subtracting or adding a fraction
For all intents and purposes, nothing. No one is capable of measuring the additional mass gained by adding electrons - especially since that would attract positive charges.
The nucleus contains protons, which are positively charged, and neutrons, which have no charge. The nucleus has a charge equal to the sum of all of the protons, so the nucleus is therefore always positively charged.
For the employee - it will be added to his/her net income For the employer - it will be subtracted from their net income
if two forces act in same direction they r added and if they act in opposite direction they r subtracted
