If Bert the Bat travels eastward at 540 mph with a tail wind of 6 mph. What is his actual speed?
Answer:
12 mph
Explanation:
1. define what an ion is (make sure electrons are part of the definition)
2. explain (in terms of electrons) how the sodium is becoming a positive ion
3. explain (in terms of electrons) how the chlorine is becoming an a negative ion
4. Explain why the difference in charges causes them to become attracted and bond to make NaCl, also known as table salt.
Answer:
valence shell, has eight electrons in it, so the atom becomes positively charged. ... in energies and is useful in explaining why atoms form the ions that they do. ... which we write as Na 2O. The need for the number of electrons lost
Explanation:
1. An ion of an atom is one in which the number of protons and electrons is not the same. If there are more protons than electrons, an atomic ion has a positive charge and is called a cation. If there are more electrons than protons, the ion has a negative charge and is called an anion.
2. Such bonds are created when the outermost electrons of one atom (such as sodium) are transferred permanently to another atom (such as chlorine). The atom that has lost an electron becomes a positively charged ion (called a cation), while the atom that picks up the extra electron becomes a negatively charged ion (called an anion).
3. For a chlorine atom to become a chloride ion, it must gain an electron. The chloride ion has a negative charge and is written as Cl-. Chlorine gains an electron because it has seven valence electrons, and to be a full octet, it gains an electron. A chloride ion is called an anion. Its electron configuration is 1s2 2s2 2p6 3s2 3p6.
4.Ionic bonds are also formed when there is a large electronegativity difference between two atoms. This difference causes an unequal sharing of electrons such that one atom completely loses one or more electrons and the other atom gains one or more electrons, such as in the creation of an ionic bond between a metal atom (sodium) and a nonmetal
hope this helps
have a good day

Balance the follwing equation:
BLANK C+ BLANK H(2) -> BLANK CH(4)
Everything in partnethesis are subscripts.
Thanks!
Answer:
- in order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side.
equation: (given)
__ C + __ H2 --> __ CH4
C = 1 | C = 1
H = 2 | H = 4
so, here we can see that the number of hydrogen (H) atoms are NOT equal, which means we have to put a number infront of the compounds inorder to balance it. this means putting a coefficient.
equation: (balanced)
C + 2H2 + CH4
- the only thing added was the 2.
-- let me know if you have any questions about this.

What are the outermost electrons of an atom
Answer:Valence Shell
Explanation: The Valence Shell is the outermost orbital of an atom. The Valence Shell electrons are used in making chemical bonds and are the reason the atom has its physical and chemical properties.
