True. Both the strontium ion (Sr2+) and xenon (Xe) have the same number of electrons when considering the ionization states: 54 electrons. This means they are isoelectronic.
54
yes,it is true...... 5.4mm = 54 cm
50 is even 25x2= 50 * * * * * True, but the question is about 54. 54 is also composite: 54 = 2*27
yes
yes but only whole numbers for example 2 - 3 - 6 - 9 - 54 - 111 are all integers 2.5 - 6.9 - 8.1 are not
Yes, that is false.
Atomic number is the number of protons in an atom. If the atomic number is 54, then there are 54 protons. If it is a neutral atom, it will also have 54 electrons.
No. 54-30=24 24<1 is false
