WitrynaThe following general trends are observed as you go across period 3 from left to right: (a) atomic number, and therefore charge on the nucleus (nuclear or core charge) increases. (b) number of valence electrons increases. (c) atomic radius decreases. (d) first ionisation energy increases. (f) electronegativity increases (excluding argon) (g ... Witryna27 mar 2024 · As we know that, there are eight elements in third period which are as follows:-. -Sodium (Na) is the alkali metal. -Magnesium (Mg) is an alkaline earth metal. -Aluminum (Al) is also a metal. -Silicon (Si) is the semiconductor, or can say metalloid in the 3 r d period. -Phosphorous (P), sulphur (S) and chlorine (Cl) are the non-metals.
Witryna24 mar 2024 · 2nd shell can hold 8 electrons. 3rd shell can hold 18 electrons. 4th shell can hold 32 electrons. Now the atomic number of Boron (B) is 5. Hence, boron element has the electrons arrangement 2, 3. This electron arrangement indicates that the outermost orbit of Boron (B) has 3 electrons. Hence, it lies in group 13.
WitrynaAnd so let's move on to the concept of periods. A period is a horizontal row on the periodic table. And so, if I look at period 1, and I just move across my periodic table, hydrogen is in the first period and so is helium. I move on to the second period, so lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
