What is radiums group?
Radium is a member of Group 2 on the periodic table, known as the alkaline earth metals group. This group includes elements such as beryllium, magnesium, calcium, strontium, and barium. Radium is a highly reactive metal that is radioactive.
What era makes up 88 percent of earths history?
The Precambrian era makes up about 88 percent of Earth's history. It started with the formation of the Earth around 4.6 billion years ago and lasted until about 541 million years ago.
How long does it take mercury to complete one revolution?
Mercury completes one revolution in about 88 Earth days. This is due to its slow rotation. Mercury is a terrestrial planet that is the nearest to the sun. A day on Mercury is about 58.5 Earth days.
What metal has been recycled with the greatest success?
Steel is the most recycled metal with the greatest success. It is highly recyclable and can be melted down and reused without losing its quality. Approximately 88% of steel is recycled globally.
About 88 percent of geologic time is represented by the time span called what?
The Precambrian Eon represents about 88 percent of geologic time on Earth. This eon includes all time prior to the Paleozoic Era and spans from the formation of the Earth about 4.6 billion years ago to the beginning of the Paleozoic Era around 541 million years ago.
Is an alkaline metal with a mass of 88?
calcium, :) im very smart
What is the most reactive alkaline earth metal?
Radium (Ra), atomic number 88, is the most reactive alkaline earth metal. It has the most energy levels of all the alkaline earth metals therefore it's electrons are more easily taken away.
What is the alkaline earth metal with the largest atomic radius?
Radium (Ra) Z = 88.
Which member of alkaline earth metal is least reactive?
Look at any periodic table: Beryllium #4 Magnesium #12 Calcium #20 Strontium #38 Barium #56 Radium #88
What place on the periodic table does radium belong in?
Oh, dude, radium is like that cool kid hanging out in Group 2 of the periodic table, also known as the alkaline earth metals. It's chilling right below barium and above francium, just doing its thing, being all radioactive and stuff. So yeah, radium is like the rockstar of Group 2.
How many electrons do alkaline earth metals have?
Each has 2 valence electrons but the number of total electrons varies with each metal. Here they are for each metal. Beryllium: 4 Magnesium: 12 Calcium: 20 Strontium: 38 Barium: 56 Radium: 88.
What element is an alkaline earth metal is very toxic?
Barium is an alkaline earth metal that is very toxic, especially in its soluble forms. Ingesting or inhaling barium compounds can lead to serious health issues such as respiratory problems, muscle weakness, and cardiac irregularities. Barium poisoning can be fatal if not treated promptly.
What is the number of atomicity of element radium?
Radium (Ra) has an atomic number of 88, which means it has 88 protons in its nucleus. In its neutral state, it also has 88 electrons. Radium is an alkaline earth metal and is known for its radioactivity. Its most stable isotope is radium-226.
What is the protons of radium?
Radium has an atomic number of 88, which means it has 88 protons in its nucleus. This characteristic defines it as an element and determines its position on the periodic table. Radium is a radioactive alkaline earth metal, and its isotopes have various applications in medicine and industry.
Is radium a compound or a element?
Radium is a chemical element, not a compound.
What is strontiums mass number?
Strontium is a metal element. Atomic mass of it is 88.
What does an average atom of radium have?
An average atom of radium has an atomic number of 88, which means it has 88 protons in its nucleus. It also typically contains 138 neutrons, resulting in its most stable isotope, radium-226. Radium is an alkaline earth metal and is known for its radioactive properties, emitting alpha particles and gamma rays as it decays. Additionally, it has an atomic mass of approximately 226 u (atomic mass units).
