What is the symbol for carbon on the periodic table? What is the symbol for Carbon in the periodic table? What is the name of an element that has its electron configuration ending in 3p5? \\ A. sulfur B. chlorine C. arsenic D. bromine ...
Sodium chloride is a compound in which one sodium ion is ionically bonded to one chloride ion. These two atoms readily bond with each other due to the instability of their outer electron shell. Sodium has one electron in its outer shell and chlorine has seven, making them both unstable. By...
So bromine has 35 protons and 35 electrons, but 45 neutrons. Platinum has 78 protons, 78 electrons, and 117 neutrons. The number of protons in an atom is called the atomic number and it tells you what type of atom you have. An atomic number of 1 means the atom is hydrogen, atomic ...
a考察了不同的实验条件下(如溴离子浓度、pH和反应时间) Inspected under the different experimental condition (for example bromine ion concentration, pH and reaction time)[translate] a把你的相片发来看看 Sends in yours photograph has a look[translate] ...
Normally, an atom has the same number of protons and electrons; their positive and negative charges balance out exactly so the atom is electrically neutral. However, if it loses or gains electrons, chemists call it an ion. Ions are more chemically active than neutral atoms because the charge...
Electron Sea Model: The metallic bond, a force that holds together metals, can be explained through the electron sea model, which can also explain the physical properties of the metals. Answer and Explanation:1 In a metal, the atoms are bonded together via the metallic bond, which is differe...
Toothpaste, which comes in many different varieties, is one of the most commonly used household items. It is used to maintain oral hygiene, and an important element is added to toothpaste to help with that. Answer and Explanation: Learn more about this topic: ...
The following are examples of NOT compounds.Br2 , bromine, is a diatomic element, or a molecular element. Only one element is in its structure though, so it is not a compound. Ar , argon, is an atom; thus, it cannot be multi-atomic, and consequently is not a compound. ...
There are many different types of activators used, with common ones being organic acids, monobasic and dibasic organic salts, compounds containing chlorine or bromine, amides, and more. Activators are helpful but corrosive, and should always be removed from the circuit board to improve the ...
What are the properties of bromine? What are the properties of water that are due to hydrogen bonding? What are the physical and chemical properties of halogens? What are examples of acidic and basic salts? What is the definition of basicity?
