Answer:

Explanation:

Symbol: K

Protons = 19

Electrons in an atom: 19

Neutrons: 39 - 19 = 20

Draw the nucleus at the center. Label it with 19 Protons and 20 Neutrons.

Draw a circle around the nucleus.

Put two dots opposite each other on the circle's circumference.

Draw another circle with its center at the nucleus bigger than you first circle.

Space 8 electrons around the circumference.

Draw a third circle like the other 2 only bigger.

Space 8 electrons around this circle's circumference.

Draw 1 more circle bigger than the third circle.

It has 1 electron.

Which three statements about gravity and the formation of the solar system
Delicious77 [7]

Answer:

B. Gravity held the pieces of forming planets together.

c. Gravity pulled most of the matter into the center of the solar system

D. Gravity caused the planets and Sun to have spherical shapes.

Explanation:

When a collection of grains pulled together by their gravitational forces would keep in by the gravity of a star, it would eventually became bigger to the point a planet was formed.

The sun's strong gravitational force pulled most of the matter around it to the center of the solar system.

The spherical shape of planets is a result of their gravity pulling equally from all sides, shaping it into a sphere.
