There is no element with one valence electron and six energy levels. Only two valence electrons and six energy levels.
Answer:
Calcium
Explanation:
A: Calcium is a group 2 element with two valence electrons. Therefore, it is very reactive and gives up electrons in chemical reactions. It is likely to react with an element with six valence electrons that “wants” to gain two electrons. This would be an element in group 6, such as oxygen.
velocity= distance / time
your distance is 180 miles
your time is 3 hours
180 divided by 3 = 60
Answer:
irritate people's breathing, ling cancer, asthma
Explanation:
Particulate matter in the air decreases life expectancy according to many researchers. Pollutants such as ozone irritate people's breathing, trigger asthma symptoms and cause lung and heart diseases. Exposure to environmental tobacco smoke causes many severe respiratory health problems such as asthma and lung cancer.
Covalent bonds are formed when two non metal atoms share an electron. The atoms either give up or gain an electron, due to the outer shell being unstable.
