The radius of an atom is closest in size to a

Answers

Answer 1

Answer:

Answer:

Explanation:

The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Three widely used definitions of atomic radius are: Van der Waals radius, ionic radius, and covalent radius.

Why is sodium more reactive than magnesium

Answers

Answer:

Mg has two valence electrons

Explanation:

Na has only one valence electron, so it readily donates that electron to other atoms to achieve an octet.

Mg must lose two valence electrons to get an octet. It takes extra energy to remove the second electron. In addition, the two electrons are in a filled s subshell, which has added stability.

That is because Sodium it is more up in the scale unlike Magnesium. Sodium’s radioactive because it has a lesser number then Magnesium, Sodium has 1 and Magnesium is 2.

A bowling ball is pushed with a force of 22.0 N and accelerates at 5.5m/s. What is the mass of the bowling ball

Answers

Hello!

Data:

F (force) = 22.0 N
m (mass) = ? (in Kg)
a (acceleration) = 5.5 m/s²

We apply the data to the Resultant Force formula, we have:

$F =m*a$

$22 = m*5.5$

$5.5 m = 22$

$m = (22)/(5.5)$

$\boxed{\boxed{m = 4\:Kg}}\end{array}}\qquad\checkmark$

I hope this helps. =)

Which of these did your answer include?Each hydrogen atom is bonded to the oxygen atom with a single bond. The oxygen atom has two lone pairs. The molecule is bent. Oxygen is more electronegative than hydrogen. Each O-H bond is polar. The molecule is asymmetrical. The asymmetry and the polar bonds produce an overall molecular dipole. The oxygen atom has a partial negative charge, and the hydrogen atoms have a partial positive charge.
