How are elements labeled on the periodic table that have the same number of<br> valence electrons?
aksik [14]

Answer:

Explanation:

Elements that have most similar properties were placed in the same group on the periodic table and this is done based on the number of valence electron each of the element posses which allow them reach in a similar manner as a member of the same family. A group of element is placed on a a vertical column of the periodic table.

For all element with one valence electron they are labelled with 1A on the group, and are usually the first column followed by 2A until group 8.

1A element are known to be very reactive and form compounds with similar properties with other elements.

Horizontal lines that represent different climate zones are called
Neporo4naja [7]

Answer:

Horizontal lines that represent different climate zones are called latitude.

Explanation:

Latitude is the distance that exists between a point on the Earth's surface to the equator, counted by the degrees of its meridian. That is, it is the distance, measured in degrees, that exists between any parallel and the line of the Equator. The latitude of a point is measured to the North or South of the zero parallel and its value can vary between 0 ° from the equator to 90 ° N from the North pole or 90 ° from the South pole.

Climate is related to latitude because it sets the amount of solar energy that a given region or place receives. Places located at high latitudes (far from the Ecuador) receive less sunlight than places located at low latitudes (near the Equator). Thus, cities distant from the equator and close to the poles have a cold climate, while at low altitudes there are high temperatures and a hot or tropical climate.
