Explanation:

1) region outside the nucleus divided into energy levels : electron cloud

Energy levels are specific spherical orbitals around the nucleus. The region of maximum probability of where an electron is located is called an electron cloud or orbital.

2) located in the outermost energy level, determines how element will react chemically with other elements: valence electrons

Valence electrons are electrons in the outermost energy shell of an atom. They determine whether an atom will react chemically with other elements of not.

3) outermost energy level : valence shell

The valence shell where the outermost electrons are located is the outermost energy level.

4) atoms that have the same number of protons but different numbers of neutrons : isotopes

Isotopes are atoms having the same number of protons but different number of neutrons. They generally have the same chemical properties. They have the same atomic number but different mass number.

5) located in the nucleus, neutral or no charge : neutrons

Neutrons are subatomic particles in the nucleus with no charges on them.

6) located outside the nucleus, negative(-) charge : electrons

Electrons are subatomic particles that carries negative charges

7) located in the nucleus, positive(+) charger: protons

Protons are positive charges in the nucleus of an atom.

Explanation:

One common property with all halogens in group 7 is that they are all non-metals.

Fluorine, chlorine, Bromine and Iodine are classified as non-metallic elements and they have a high electronegativity.

In chemical reactions, they are very reactive because they require just one electron to complete their octet configuration and be isoelectronic with noble gases.

The most prominent observation from halogens is that they all non-metallic in nature.

Calculate the force of gravity between planet X and planet y if both planets are 3.75 X 10^11 m apart, planet X has a mass of 1.

GenaCL600 [577]

So, the force of gravity that the asteroid and the planet have on each other approximately $\boxed{\sf{2.9 \times 10^{17} \: N}}$

<h3>Introduction</h3>

Hi ! Now, I will help to discuss about the gravitational force between two objects. The force of gravity is not affected by the radius of an object, but radius between two object. Moreover, if the object is a planet, the radius of the planet is only to calculate the "gravitational acceleration" on the planet itself,does not determine the gravitational force between the two planets. For the gravitational force between two objects, it can be calculated using the following formula :

$\boxed{\sf{\bold{F = G \times \frac{m_1 \times m_2}{r^2}}}}$
