How is electron movement related to the bonding in sodium chloride?

A) The atomic orbitals overlap and share electrons causing an ionic bond to form.
B) Electrostatic sharing of electrons between atoms allows covalent bond formation.
C) Electrons exchange creating ions to form an ionic bond by electrostatic attraction.
D) Orbital overlap occurs between the atoms to exchange electrons to form the covalent bond.

An object starts from rest at point f and speeds up continuously as it moves around an oval. a. choose a point about 1/8 th of the way around the oval from point f, and label it point g. draw a vector to represent the velocity of the object at point g. b. determine the change in velocity vector   between points f and g.

What do elements in a family tend to share. a.) similar periods b.) similar groups c.) similar atomic symbols d.) similar chemical properties and characteristics

7. see worksheet 1 for values of variables x1, x2 and x3 and answer the following questions: a. for each variable find the mean, median, coefficient of skewness, range and population standard deviation. b. compared to variable x1, how are the mean and median affected by extreme values (outliers) seen in x2 and x3. c. is the median or mean the better measure of location for x2 and x3? explain. d. explain the differences in the magnitudes of the skewness coefficients for the three variables. e. what is the relationship between the range and standard deviation looking across the three variables?
