How many protons does Se-75 have?
Look it up on the periodic table. It's #34, signifying that it has 34 protons.
What element has a greater number of protons potassium or selenium?
Selenium has 34 protons and potassium has 19. The proton number corresponds to the position of the element in the periodic table.http://www.rsc.org/periodic-table/?gclid=CjwKEAjw2MOhBRCq-Nr87_j-lDASJAAl4FNhssVbsyCT_UjwmmrpVjUngib6tHybHy88YrC1gH_1shoCZDzw_wcB
In what group is selenium in the periodic table?
Selenium (Se) is in oxygen family (group 16 or VIA) and in 4th period.
Do neutrons differ in elements?
sure, neutrons differ in elements From the periodic table, they are fixed. However, there are also isotopes, where the element remains the same and contains the same number of protons but with different number of neutrons. For example, sulfur is present as 32S, 33S, 34S and 36S in nature. This means that the number of neutron + the number of proton in a sulfur atom can be 32, 33, 34 or 36. However, the constant in the 4 isotopes is that all of them contain only 16 protons.
How many protons neutrons and electrons are in a selenium atom?
Selenium (Se) has an atomic number of 34 which means in a balance atom Se will have 34 protons and 34 electrons then Se has a mass of 79 so to get the neutrons we minus the protons from the mass and we get 45 final answer: Neutrons: 45 Protons:34 Electrons: 34
What is the 34th element on the periodic table?
The element with atomic number 34, selenium.
How many protons does Se-75 have?
Look it up on the periodic table. It's #34, signifying that it has 34 protons.
Which elements are solids at room temperature on the periodic table?
Elements 3-6; 11-16; 19-34; 37-53; 55-79; 81-85; 87-92
Which element has 30 protons?
30 protons means element 30 from the periodic table, which is Zinc. Although it usually doesn't have 30 neutrons, and I doubt that would be a stable isotope. Stable zinc isotopes have 34 and 36 neutrons.
What element has a greater number of protons potassium or selenium?
Selenium has 34 protons and potassium has 19. The proton number corresponds to the position of the element in the periodic table.http://www.rsc.org/periodic-table/?gclid=CjwKEAjw2MOhBRCq-Nr87_j-lDASJAAl4FNhssVbsyCT_UjwmmrpVjUngib6tHybHy88YrC1gH_1shoCZDzw_wcB
How many groups of 34 go into 254?
254 ÷ 34 = 7.4705882
In what group is selenium in the periodic table?
Selenium (Se) is in oxygen family (group 16 or VIA) and in 4th period.

What is oxygen family number and name?
The oxygen family is a group of elements located in Group 16 (also known as Group VI A) of the periodic table. The elements in the oxygen family share similar chemical properties and characteristics. The elements in the oxygen family are: Oxygen (O) - Atomic number 8 Sulfur (S) - Atomic number 16 Selenium (Se) - Atomic number 34 Tellurium (Te) - Atomic number 52 Polonium (Po) - Atomic number 84 These elements have six valence electrons in their outermost energy level and often form -2 ions by gaining two electrons to achieve a stable electron configuration.
What are the ratings and certificates for New Girl - 2011 Table 34 2-16?
New Girl - 2011 Table 34 2-16 is rated/received certificates of: USA:TV-14
The mass of a Cr is 52 amu its atomic number is 24 how many neutrons are in its nucleus?
Since n + p = m, it follows that neutrons = 54 - 24 = 30,because number of protons (p) is the atomic number (34)! That's how the periodic table is organized.
How did plutonium get its name?
suggested that element 94, being the next element in the series, be named for what was then considered the next planet, Pluto.[4][note 2] Seaborg originally considered the name "plutium", but later thought that it did not sound as good as "plutonium."[33] He chose the letters "Pu" as a joke, which passed without notice into the periodic table.[note 3] Alternate names considered by Seaborg and others were "ultimium" or "extremium" because of the now-discredited belief that they had found the last possible element on the periodic table.[34] suggested that element 94, being the next element in the series, be named for what was then considered the next planet, Pluto.[4][note 2] Seaborg originally considered the name "plutium", but later thought that it did not sound as good as "plutonium."[33] He chose the letters "Pu" as a joke, which passed without notice into the periodic table.[note 3] Alternate names considered by Seaborg and others were "ultimium" or "extremium" because of the now-discredited belief that they had found the last possible element on the periodic table.[34]
