What is Y in periodic table?
Y is the symbol for the element yttrium.
What is the identity of each element?
The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.

How many neutrons does Y have?
50 neutrons Y has a mass number close to 90 and has 50 neutrons in its nucleus.
What is the atomic mass symbol for Y?
Yttrium is a chemical element with symbol Y and atomic number 39.
What is the identity of Z?
And the number of protons gives Z , the atomic number, which defines the identity of the element: Z=1 , the element is hydrogen; Z=2 , the element is helium; Z=3 , the element is lithium;…………
What is the identity element of R?
For instance, R mathbb R R is a ring with additive identity 0 0 0 and multiplicative identity 1 , 1, 1, since 0 + a = a + 0 = a , 0+a=a+0=a, 0+a=a+0=a, and 1 ⋅ a = a ⋅ 1 = a 1 cdot a = a cdot 1 = a 1⋅a=a⋅1=a for all a ∈ R .
What is the electron configuration of Y?
(Kr) 4d1 5s2Yttrium / Electron configuration
What is the valency of element Y?
3 (d) The valency of Y is 3. The number of electrons lost or gained by one atom of an element to achieve the nearest inert gas configuration gives us the valency.
How many protons does Y+ have?

What is the general name of the group of element Labelled Y?
yttrium (Y), chemical element, a rare-earth metal of Group 3 of the periodic table. Yttrium is a silvery white, moderately soft, ductile metal. It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3.
Why is yttrium called yttrium?
Yttrium was named for Ytterby. In 1843, a Swedish chemist named Carl Gustaf Mosander studied yttrium samples and discovered they contained three oxides. At the time they were called yttria, erbia and terbia. They are now known as white yttrium oxide, yellow terbium oxide, and rose-colored erbium oxide, respectively.
What is the additive identity of 4?
The additive identity for any real number is 0.
What is the additive identity of 8?
zero So, zero is the additive identity.
How do I find my identity element?
Identity element of Binary Operations
- Addition. + : R × R → R. e is called identity of * if. a * e = e * a = a. i.e. …
- Multiplication. e is the identity of * if. a * e = e * a = a. i.e. a × e = e × a = a. This is possible if e = 1. …
- Subtraction. e is the identity of * if. a * e = e * a = a. i.e. a – e = e – a = a.

What type of element is yttrium?
rare-earth metal yttrium (Y), chemical element, a rare-earth metal of Group 3 of the periodic table. Yttrium is a silvery white, moderately soft, ductile metal. It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3.
What is yttrium named after?
New elements were later isolated from each of those oxides, and each element was named, in some fashion, after Ytterby, the village near the quarry where they were found (see ytterbium, terbium, and erbium).
What is the additive identity of 2?
(d). 2. Hint: An identity is a number which when operated on another number does not change the number. Additive identity is the number which when added to any number will give the same number as the result.
What is the additive identity of 7?
The additive identity of -7 is 7. Hope it helps!!
What is the additive identity of 5?
0 What is additive identity? Additive identity is the value when added to a number, results in the original number. When we add 0 to any real number, we get the same real number. For example, 5 + 0 = 5.
What are identity properties?
The identity property of 1 says that any number multiplied by 1 keeps its identity. In other words, any number multiplied by 1 stays the same. The reason the number stays the same is because multiplying by 1 means we have 1 copy of the number.
