How does an element pick up extra electrons or loss an electrons to form ions?
in a chemical reaction, if one atom has 1 electron in it's outer shell, and another has 7 , in a chemical reaction the one with 1 will 'give' it to the one with 7, because all atoms want 8 electrons in the outer shell.
When alpha particles pick up electrons they become?
When alpha particles pick up electrons, they become helium atoms. Alpha particles are essentially helium nuclei without electrons, so when they pick up electrons, they form stable helium atoms with a balance of protons and electrons.
Is helium produced only in the cores of stars?
No. Helium nuclei are a common product of nuclear fission, as takes place in nuclear explosions and reactors. These nuclei then pick up electrons from other atoms and become whole helium atoms.
Do all atoms have valence electrons?
It depends on the atom. An atom is made of 3 subatomic particles- a negatively charged electron, a positively charged proton, and a neutral neutron. If the number of electrons and the number of protons are different, then the atom has a net charge. If the number of electrons and the number of protons are the same, then the atom is said to be neutrally charged. Changing the number of neutrons affects the mass and therefore important traits of each atom, but does not affect its charge. Atoms that have a net charge are called 'ions.'
Does the number of electrons in an atom ever change?
This is kind of a trick question...An atom has a fixed number of electrons. However, some atoms are predisposed to give up or accept electrons to ensure their outer shell is full. When that happens, though, they are no longer atoms, but become ions. An ion is a charged atom.For example: Chlorine has an outer shell that is one electron short of a full shell. It readily accepts an electron from anything that will donate it. In doing so it goes from being a Chlorine atom to a Chlorine ion with a negative charge.Sodium has one electron in its outer shell. If it loses it it has a full outer energy shell and is more stable. It readily goes from being a sodium atom to being a sodium ion with a positive charge.Hence the trick question. Yes an atom can change the number of electrons it has, but as soon as it does so it stops being an atom and becomes an ion. Or, conversely, no, an atom cannot change its number of electrons because when it does so it stops being an atom and becomes an ion. Take your pick!

What two things can atoms do to achieve a stable octet of electrons?
They can either pick the electrons from around them, or start throwing them off in a measure of radioactivity.
When Barium and Oxygen react to form an ionic compound does Barium atoms lose 2 electrons and form a cation?
Yes, in the reaction between barium and oxygen to form an ionic compound, barium atoms will lose 2 electrons to form a Barium cation with a 2+ charge. Oxygen will gain those 2 electrons to form an oxide anion with a 2- charge.
Is helium produced only in the cores of stars?

How do electrons separated from their atoms using pressure-compressing a crystal as in sound pick-ups?
Your phrasing is not very coherent, however, you are talking about the piezoelectric effect. Try looking that up on wikipedia.
Is helium a product of radioactive decay?
Yes. Alpha particles can be a product of radioactive decay, and alpha particles are simply Helium nuclei. Unless they interact with other atoms, they will tend to pick up stray electrons (they need two) and become stable 4He atoms.
What kinds of objects pick up electrons easily?
These are electrically positive objects.

What type of elements occur in a covalent bond?
Elements do not "occur" in bonds. Instead, elements form bonds between themselves. If the question means "Between what types of elements are covalent bonds likely to form?", the answer is "elements with very similar electronegativities". The smallest possible difference between electronegativities is that between two atoms of the same element, such as is present in the diatomic elements hydrogen, oxygen, nitrogen fluorine, chlorine, bromine, and iodine and in the polyatomic element carbon in its diamond crystal form.
Is a pick really called a pick or is it really called a pickaxe?
Its called a pickaxe thats the full name for it. PICK is short for pickaxe. Like Will and William etc...
