How many valence electrons does magnisium oxide have?
MgOMagnesium: 2 Valance Electrons (Charge is +2)Oxide: 6 Valance Electrons (Charge is -2)Hint: Oxide has a charge of -2 and so does Oxygen. Check the periodic table for the elements that have a -2 charge (group 16) and you will find oxygen as the first element in that group. Periods define how many energy levels the element has, just so you know. Oh and this is ionic.Hope this helps!
What is the charge of Mg?
Mg or the element magnesium has only one possible charge of +2. Just a hint but all elements in group 2 have a charge of +2 ie. Be, Ca, Sr...
What makes something an acid hint what does it release in water?
When something dissociates in a solution is referred to an acid and it releases protons H+ in water.
Which element has 3 electrons in the 2p sublevel?
Aufbau says that the sublevels fill 1s2, 2s2, 2p6. That would mean that you must have filled 1 and 2 s (=4) and 3 more. Last I checked, 3 + 4 = 7. Which element has 7 electrons? I'll give you a hint: its atomic number is 7. Another hint: its symbol is N.
How does boron's position in the periodic table hint that it is stable when bonded to only three atoms?
Boron tends to form molecules in which it is surrounded by only six valence electrons. Boron only has three valence electrons, and fluorine already has seven of the eight electrons it needs to fulfill its octet to be stable. Hope it helps!
Is it true that unlike protons and electrons neutrons have no charge?
Yes that's true! You got that one right! :)Here's a helpful way to help you remember this:Neutrons have NO charge. (hint: here's way to remember it. "N" in neutrons for "N" in "NO")Protons are positive charge ("P" from protons, "P" for positive)Electrons are negative charge (well if you remember the other 2, then this one obviously got to be negative. just remember the others, and that electron is opposite charge of proton)..Well that's how I remembered it back then, made it easier for me.
Does the sum of the protons in an atom equal the sum of the electrons?
Protons minus neutrons doesn't mean anything in chemistry. Protons plus neutrons gives the mass number. Protons minus electrons gives you the charge of an atom(ion). The number of protons are equal to the number of electrons in a neutral atom and the proton number is equivalent to the atomic number.
What is the difference between mass and atomic numbers?
The atomic number gives you a hint of how many protons are in the atom. While mass is the weight of the whole atom( including protons, electrons, and neutrons).
determine the subatomic particle ( electron, protons, neutron)?
For Example:- Calculate the number of protons, electrons, neutrons in Bromine with atomic number 35 and mass number 80. Hint: In order to answer this question you must recall the periodic properties and mole concept chapter in which you have done conversions regarding the number of moles, number of atoms, number of electrons, protons, and neutrons in a sample of given atomic number and mass number. Firstly, find the number of protons and the same number of electrons will be there and the sum of protons and neutrons form the mass number and you will get your answers. Complete step by step answer: Step 1: In this step we will find the number of protons of the given sample: Number of protons of a sample = Atomic Number of the element = 35 Step 2: In this step we will find the number of electrons of the given sample: Number of electrons of a sample = Number of protons = 35 Step 3: In this step we will find the number of neutrons of the given sample: Number of neutrons of a sample = (Mass number - Atomic Number) of the element Number of neutrons of a sample = 80 – 35 = 45 So, here we got our required values. The values are: No. of proton p = 35 No. of neutron n = 45 No. of electron e = 35 Note:The number of protons in the nucleus of the atom is equal to the atomic number (Z).The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
What element has 20 protons and is found in teeth and bones?
Calcium

Who does Kobe Bryant like to play against?
women who dont want to be with him (Hint the rape charge)
Why is there 118 electrons in the element chromium?
Who told you that chromium had 118 electrons - there are only 24. Check it out with Wikipedia. There you find the element that really has 118 electrons. Happy hunting. (PS - Hint - there is a very close correlation between the number of electrons and the atomic number of the element.)
What two atoms could be the before and after of alpha ejection?
The before and after atoms in alpha ejection can vary, but commonly involve a heavy radioactive nucleus undergoing decay. The before atom is typically a parent atom with a high atomic number, such as uranium or radium, while the after atom is the result of the ejection of an alpha particle (consisting of two protons and two neutrons), which is typically a daughter atom with an atomic number two less than the parent atom.
Is the Motorola hint a good phone?
Well...the thing is that sometimes it is a good phone. but sometimes i want to throw it out the window!!!!! so no the Motorola hint is not a good phone. because after they die completely....he don't charge at all!!!
