Answer:
Bromine (35) 1s²2s²2p63s²3p⁶3d¹⁰ 4s² 4p⁵
Magnesium(12) 1s2 2s2 2p6 3s²
Selenium (34) 1s²2s²2p63s²3p⁶3d¹⁰ 4s² 4p4
Explanation:
In the SPDF electronic configuration, the S orbital can accommodate maximum of 2 electrons,
The P orbital has maximum of 6 electrons
The D orbital has maximum of 10 electrons
The F orbital has maximum of 14 electrons
Bromine with atomic number 35 belongs to group seven(7) period four (4) it ground state electron configuration is 1s²2s²2p63s²3p⁶3d¹⁰ 4s² 4p⁵
Magnesium with atomic number 12 belongs to group one, period two(2), it ground state electron configuration is 1s2 2s2 2p6 3s²
Selenium has atomic number of 34, it belongs to group six(6), period four(4) it electronic configuration is 1s²2s²2p63s²3p⁶3d¹⁰ 4s² 4p4
Answer:
8.73
Explanation:
when you are adding or subtracting numbers, the sigfig (significant figure) is based on how many numbers after the decimal. with this info, we can see that 15.67 has 2 sigfigs and 6.943 has 3 sigfigs. when you subtract normally, you would get 8.727, which has 3 sigfigs, so you would round the last 7 up to get 8.73 with 2 sigfigs!
also it is to 2 sigfigs because we know that we go by the least number of sigfigs. hope this helped!
