Group 1 elements are comprised of: (1) hydrogen, sodium, lithium, potassium, rubidium, caesium, and francium. The tendency of these atoms is to lose one of their electrons such that they become charge +1.
Group 5 elements contains the vanadium, niobium, tantalum, and dubnium. It is quite hard to predict the oxidation number of these elements such that it will be hard to determine the number of atoms needed to react with them. Their valence electron is 5, and they react by losing them. Hence, in order to reach the octet rule, 3 group 1 elements should be reacted.
Answer: Reflection is the change in direction of a wavefront between two different media so that the wavefront returns into the medium from which it originated.
Step-by-step explanation:
Y=-2x+4 the first blank will be your slope and the second blank will be where your line crosses the y intercept
Answer:
Use area of trap formula and special right triangles
Step-by-step explanation:
A = (.5)(10 + 18)(5)
5x + 6 = 1
Subtract 6 from both sides.
5x = -5
Divide from both sides.
x = -1 (ANSWER)
hope this helps!!
