Which atom has 49 protons?
if im correct u will have 126 elctrons no you will have 49 you must have the same amount if the atom is to have no charge. Protons are positive and electrons are negative, there for they have the same amount
When does a motor not need a neutral wire?
If the motor is operated from a three phase three wire distribution system the motor will not need a neutral wire.
Do you need dedicated neutral for 50hertz 220volt?
Yes
What would be formed if one proton is added to the lithium atom?
You'd end up with a charged beryllium atom (to which you'd need to add an electron to make it neutral).
Do you need a neutral wire for a light to work?
The neutral wire is the return wire back to the distribution panel from the load. Without this return wire no load will work.
What is the last part in a chemical formula of a binary ionic compound?
balancing the charges on the ions to make a neutral compound
What are the charges for ammonium and sulfite?
Ammonium is NH4 + and Sulfate (I think you meant sulfate anyway) is SO42-. To make a neutral ion you need two ammoniums and one sulfate. It looks like this: 2NH4SO4 or (NH4)2SO4.
How many electrons would you need to make calcium neutral?
The atomic number for calcium 20 so to make it neutral it should loss 2 electrons
How much do you need to subtract from 316 to make 5?
316 minus 311 = 5
How much do you need subtract from 436 to make 7?
436 minus 429 = 7

Ionic compounds are electrically?
Charged i will leave urs but this is the correct answer Neutral u guys need 2 make up ur mind
How do you beat the subway guy on poprtropica?
That is easy all you need is to avoid him when he charges then make him slip in the water
How many ions of magnesium and oxygen would you need to make an electrically neutral compound?
one of each
If element X forms the oxides XO and X2O3 the oxidation numbers of element X are what?
Oxygen forms a -2 ion. x0 - x= +2. The compound overall needs to be neutral, so you add up all the charges from the oxygen and add whatever you need to make it neutral. eg: FeO - oxidation state of iron = +2, since oxygen forms -2 and compound is overall neutral. Fe2O3 - -6 from the oxygen. So you need to add +3, and there are two Fe's so you divide it by two - therefore iron is +3. Hope that helps.
How much do you need to subtract from 256 to make 4?
256 - 252 = 4
What two subatomic particles must be the same to a maintain a neutral atom?
The question is a bit fuzzy, but I'll interpret it to mean what two particles need to be present in the same numbers to maintain a neutral atom. The answer is protons (with a positive charge) and electrons (with a negative charge). The charges for each are equal and opposite, so when they are balanced in equal numbers, the atom is electrically neutral.
