Answer:

1) group

2) period

3) numbers of valence electrons

4) increases

Explanation:

When we move in a periodic table from top to bottom or vice versa along a vertical column , it is said that we are moving along a "group" in a periodic table.

Like wise when we move in a periodic table from left to right or right to left  in a horizontal row , it is said that we are moving along a "period" in a periodic table.

The classification of elements belonging to any specific group of periodic table is dependent on the total number of valence electron. All elements of with in a group have same number of valence electrons however, the orbitals may change.

The atomic number increases while moving from left to right as the number of orbitals in which the valence electron is found also increase in the same direction.

Es una de las características de la ciencia en la cual se realizan los juicios de valor, atiende a los hechos y a la lógica. *
Cerrena [4.2K]

Answer:

razonamiento

Explanation:

La ciencia se define como una agrupación de conocimientos racionales, lógicos, comprobables y sistemáticos los cuales son obtenidos mediante el proceso de observación/experimentación y posterior razonamiento. Los conocimentos científicos permiten deducir principios y leyes que son utilizados para predecir fenómenos del mundo natural. Una característica clave de la ciencia es el uso del razonamiento lógico mediante el cual aplica el método científico para generar dichos principios y leyes. El razonamiento lógico es un proceso mental que comienza con una premisa y finaliza con una conclusión comprobable que puede determinarse como verdadera o falsa.

Use the drop-down menus to complete each statement about Steven Businger's work with volcanoes in Hawaii.
sammy [17]

1. Vog

The term vog comes from combining the words volcano and smog. The word itself is created to associate with pollution, as it is a natural pollution of the atmosphere. The vog represents the sulfur dioxide and the other gases and particles that the volcanoes release into the atmosphere when they erupt. These gases and particles further react with the moisture in the atmosphere and the oxygen while exposed to sunlight. This process causes a large natural pollution of the air in the area influenced by the volcanic activity.

2. Model

Steven Businger is a scientists that has devoted big portion of his career in examining the volcanoes and their activities. Most of his research has been on the Hawaii Islands and the volcanoes on them. With his vast experience and knowledge of the volcanic activities and their products, Businger managed to create a model that predicts how the smoke from the volcanoes spreads. This model has been very helpful as it can be used for warning the population on time, as well as using it for avoiding accidents, especially in the air traffic.

3. Sulfur dioxide

One of the gasses that is in largest quantities in the smoke produced by the volcanic eruptions is the sulfur dioxide. This gas is a natural polluter of the atmosphere, so once big amount of it is propelled into the atmosphere, it manages to have big effect over the area that is affected. It is a gas that is very harmful for the living organisms, thus for the human health as well. It is mostly damaging the respiratory system, managing to cause lot of damage that can easily be fatal if the amount of sulfur dioxide is high.
