Answer: Metals found as native minerals in nature are not highly reactive

Explanation:

Native minerals refers to minerals that are found in nature in their pure metallic form such as gold. Iron and aluminum are highly reactive metals. Highly reactive metals are far up in the activity series of metals, they have a great tendency towards oxidation. On the other hand, noble metals have less tendency towards oxidation and are found close to the bottom of the activity series for example, gold.

Al agregar 150g de una sustancia X en un recipiente que sostiene que contiene agua hasta 50, el nivel del agua aumenta hasta 120
vovangra [49]

Answer:

2,14 g / ml

Explanation:

Sabemos que el volumen de una sustancia es igual al cambio de volumen del agua cuando el objeto en cuestión se sumerge en el agua.

Dado que el volumen original del agua = 50 ml

Volumen de agua después de sumergir el objeto = 120 ml

Masa del objeto = 150 g

Ahora,

Densidad = masa / volumen

Densidad = 150g / 120-50 ml

Densidad = 150/70 ml

Densidad = 2,14 g / ml

Fluorine (F) and bromine (Br) are in the same group on the periodic table. How do atoms of these elements compare when they form
mojhsa [17]

Answer is: Both a fluorine atom and a bromine atom gain one electron, and both atoms become stable.

Fluorine and bromine are in group 17 in Periodic table of elements. Group 17 (halogens) elements are in group 17: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). They are very reactive and easily form many compounds.

Halogens need to gain one electron to have electron cofiguration like next to it noble gas.

Fluorine has atomic number 9, it means it has 9 protons and 9 electrons.

Fluorine tends to have eight electrons in outer shell like neon (noble gas) and gains one electron in chemical reaction.

Electron configuration of fluorine: ₉F 1s² 2s² 2p⁵.

Electron configuration of neon: ₁₀Ne 1s² 2s² 2p⁶.
