Is calcium a molecular or Ionic?
Ca(OH)2 is ionic. It is composed of one calcium cation, Ca2+, bonded to two hydroxide anions, OH-.
What medieval belief did Copernicus dispute?
Copernicus disputed the medieval belief that the Earth was the center of the universe, known as the geocentric model. He proposed the heliocentric model, where the Sun, rather than the Earth, was at the center of the solar system.
Does cesium gain electrons?
Cesium tends to lose electrons rather than gain them. As an alkali metal, cesium typically forms a +1 cation by losing its single valence electron to achieve a stable electron configuration.
Why did the the theory of a sun centered solar system create such alarm?
It caused such an alarm because the teaching of the geocentric theory (theory that the Earth is in the center of the universe rather than the Sun) was in the Bible, and therefore God's word, and if people thought the heliocentric (theory that the Sun is in the center of the universe rather than the Earth) they could either a) go against God's word and be punished or b) turn away from the church for being incorrect about this, ultimately leaving the Church with no money and no people. I believe Nicolaus Copernicus proposed this theory first.
What is the major factor that governs whether a solar eclipse is total rather than annular when viewed from the center of the eclipse path on Earth?
The major factor that governs whether a solar eclipse is total rather than annular when viewed from the center of the eclipse path on Earth is the relative distances between the Earth, Moon, and Sun. When the Moon is closer to Earth in its elliptical orbit, it appears larger and can cover the Sun completely, resulting in a total solar eclipse. In contrast, when the Moon is farther away, it appears smaller and cannot fully cover the Sun, leading to an annular eclipse.
Why the center of the band is used to calculate the rf value for a cation rather than the leading edge of the band?
The center of the band is used to calculate the RF value for a cation because it provides a more accurate representation of the overall migration of the ion during chromatography. The leading edge may be influenced by factors such as diffusion or interaction with the stationary phase, which can distort the true position of the cation. By using the center, you account for the spread of the band and obtain a more reliable measurement of the cation's mobility and separation efficiency.
Is boron a cation or an anion?
Boron is a metalloid element with the symbol B. In chemical compounds, boron tends to form covalent bonds rather than ionic bonds, so it does not typically exist as a cation or anion in its pure elemental form.
Is magnesium anion or cation?
i don't know go back to school:) it's a cation!

Is iodine a cation?
No, iodine is not a cation. Iodine is a non-metal halogen element that typically forms an anion in chemical reactions by gaining an electron to achieve a stable electron configuration.
What is the opposite of a covalent bond?
The opposite of a covalent bond is an ionic bond, where electrons are transferred from one atom to another rather than shared. In an ionic bond, one atom becomes positively charged (cation) and the other becomes negatively charged (anion), leading to an electrostatic attraction between the two atoms.
What is the good thing working in a small call center rather that working in a big call center?
Promotions are easier to achieve.
Is carbon dioxide a cation or anion?
Carbon dioxide is a neutral molecule. Cations have a positive (+) charge, anions have a negative charge
What is a cult center?
the center of the cult. Not the edges or outside. Not necessarily inside, but rather absolutely central, at the center most point, equally positioned in diameter from the edges of the cult.
What is a leapfrog activity center?
The Leapfrog Activity Center is not a place but rather an activity center to be used in the home for your baby. There are many different styles and they average $120-$165.
