What are incorrect formulas for elements Ar2 Fe Cu2 I2 O2?
Ar2 is incorrect. Reason; Argon is a noble gas and exists as single atoms (monatomic) . Fe is correct Iron chemically exists as single atoms . Cu2 is incorrect. Reason ; copper exists as single atoms. I2 is correct ; iodine is diatomic. O2 is correct ; oxygen is diatomic.
What is the electron configuration for Ar2?
potassium; doing the chem homework? :) Maroulis woot.
Does argon represent a molecule or an atom?
Like all the inert gases it is in atomic form. No molecules like Ar2 are possible. Atom
Can two argon atoms form a covalent bond to give ar2?
No. Argon has completely filled orbitals. It is stable and does not form compounds. Argon exists as monoatomic gas.
What are five compounds argon is in?
Short answer: It doesn't have that many; it's a noble gas. Long answer: Argon fluorohydride, HArF, has tentative stability under -233 Celsius. A few Van der Waals molecules containing argon are known (Ar2, H2-Ar, C6H6-Ar), and the fullerene (Ar@C60) is known--but the last four are not true "compounds". Argon is a noble gas, having 8 electrons in its outer electron shell, so other atoms have to force that shell to expand for any compounds to form. So, only extreme conditions with the strongest electron-drawing element in existence can crack argon.
What is the sum of the infinite geometric series?
The sum of the series a + ar + ar2 + ... is a/(1 - r) for |r| < 1

What is a AR2 dongle?
A dongle is a device that is attached to a computer's I/O (input/output) port to release access or operation of software or hardware. Without a dongle, the software or hardware is rendered useless. The term "AR2" means "Action/Replay 2", a feature used in video games to store game play, codes, characters etc. Closest match is a memory card. So, putting the two together, an AR2 dongle is hardware that unlocks features or play of game software.
What is Fibonacci sequence conclusion?
There is no conclusion to the Fibonacci sequence - it continues on infinitely. The conclusion is that successive terms tend to a constant ratio with one another. So if a is one term, the next is ar and the one after that is ar2. Then from the rule that any term is the sum of the previous two, ar2=ar +a, which means r2-r-1=0 so r =(1+sqrt5)/2 (the golden ratio). There is no end to this series.
Can two argon atoms form a covalent bond to give ar2?
No. Argon has completely filled orbitals. It is stable and does not form compounds. Argon exists as monoatomic gas.
Why is this distribution referred to as a geometric distribution?
The geometric distribution is: Pr(X=k) = (1-p)k-1p for k = 1, 2 , 3 ... A geometric series is a+ ar+ ar2, ... or ar+ ar2, ... Now the sum of all probability values of k = Pr(X=1) + Pr(X = 2) + Pr(X = 3) ... = p + p2+p3 ... is a geometric series with a = 1 and the value 1 subtracted from the series. See related links.

What does the mathematical term growth factor mean?
It is a number, r, which is greater than 1, such a given variable increases by a multiple r over each unit of time.So, over a set of times, the variable A would beA, Ar, Ar2, Ar3, ... , Arn-1, ...
What is a geometric rule for pattern?
Not sure about this question. But, a geometric sequence is a sequence of numbers such that the ratio of any two consecutive numbers is a constant, known as the "common ratio". A geometric sequence consists of a set of numbers of the form a, ar, ar2, ar3, ... arn, ... where r is the common ratio.
What is the formula to find the sum of a geometric sequence?
The formula to find the sum of a geometric sequence is adding a + ar + ar2 + ar3 + ar4. The sum, to n terms, is given byS(n) = a*(1 - r^n)/(1 - r) or, equivalently, a*(r^n - 1)/(r - 1)
