How many valence electrons does the element Zinc have??

http://answers.yahoo.com/question/index?qid=20081213134702AAWfeoT

Zinc has 2. The outermost shell contains 2 electrons. However, the third shell on zinc has 18 electrons, not 8. Zinc is a transition metal, and they do not follow those rules of placing 8 on every shell. Zinc has 2, 8, 18, 2, so it has 2 va…

how do i find how many electrons are in the outermost level of an element? is it the same as valence electrons

Q: also, how do i know which electrons are lost when an element forms a bond? and does the charge of an element change when it loses electrons in forming a bond?if you want to use an example, it would help me a lot if you used zinc 🙂

A: valence electrons = e- in outermost orbital.electrons are shared when an ionic bond is formed, no e- are lost.

A: 2 is wrong. 0.000237 is 2.37 x 10^-4#3 is wrong. 0.00000031 is 3.1 x 10^-7 (there’s 6 zeros there)#6 is wrong. There is 6.022 x10^23 atoms in 1 mole. The problem says 2.5 moles – so multiply 6.022 x 10^23 by 2.5 = 1.5 x 10^24 atoms#7 is wrong. 1 mole is 6.022 x 10^23 atoms. (9.5 x 10^24 / 6.022 x 10^23) = 15#15 is wrong. Zn has 10 d-orbital electrons. These participate in bonding along with its s electrons. The answer here is the 10 3d electrons plus the two 4s electrons = 12.#16 is wrong. Mg forms a +2 ion. I forms -1 ion, so it would be MgI2.#17 should be: H2 + Br2 —> 2 HBr. 2 is still correct, but your equation was wrong. Br2 is a diatomic molecule, just like H2.#18 is wrong. Na forms a +1 ion, O forms -2, so we need 2 Na’s 2 Na + 1/2 O2 —> Na2O but we can’t leave the 1/2 in there, multiply the whole equation by 2 to get rid of the 1/24 Na + 1 O2 —> 2 Na2O Now its balanced. Answers is 4 sodium atoms in the balanced equation.#19 is wrong. Blue litmus will turn red under acidic conditions. Nothing happens to red litmus in acid (it stays red).#20, answer should be: a salt plus water (formed in a neutralization reaction) example…. HCl + NaOH —> NaCl + H2O21. creating excess hydronium inos in water is a characteristic of ACIDS (not salts).HCl (an acid) + H2O —> H3O+ + Cl-HCl is not a salt.

Help on chemistry homework?

Q: help on these questions1.) Which of the following is the best description of how electrons are transferred in an ionic bond? A. A metal atom loses electrons and a nonmetal atom gains electrons. B. A metal atom gains electrons and a nonmetal atom loses electrons. C. A metal and a nonmetal atom lose electrons. D. A metal and a nonmetal atom gain electrons. 2.) Zinc phosphide, Zn3P2, is often used as a rat poison. Phosphorus has 5 valence electrons. How many valence electrons does each zinc atom lose? A. 1 B. 2 C. 3 D. 4 3.) Lithium nitride has the chemical formula Li3N. Rubidium is in the same chemical family as lithium. What is the formula of rubidium nitride? A. RbN B. RbN3 C. Rb3N D. Rb2N3 4.) How many covalent bonds are there in one molecule of silica, SiO2?A. 0 covalent bondsB. 2 covalent bondsC. 4 covalent bondsD. 6 Covalent bonds

A: 1. Metals lose electrons and nonmetals gain electrons2. Phosphate needs 3 electrons each totalling 6 electrons so each zinc will need to give up 2 electrons. Phosphate wants to imitate the electron configuration of Argon because noble configurations are the most stable. with P getting the extra electrons the valence shell will be 3s2 3p6, which is the same as Argon. With out the extra electrons, the P valence shell looks like this 3s2 3p3, now you can see why each phosphorus wants 3 more electrons, that will make it 3s2 3p6, just like Ar.3. Rb3N because they are in the same family and have similar chemical behaviors. Rb forms +1 ions and N forms -3 ions so you can see it takes 3 Rb’s to equal the -3 of N, this will make a neutral molecule4. 2 covalent bonds
